-/**
- * Constructs a Controller object.
- *
- * When creating a Controller object, you may optionally pass in options
- * to set the host , set the port, or select the frame event type.
- *
- * ```javascript
- * var controller = new Leap.Controller({
- *   host: '127.0.0.1',
- *   port: 6437,
- *   frameEventName: 'animationFrame'
- * });
- * ```
- *
- * @class Controller
- * @memberof Leap
- * @classdesc
- * The Controller class is your main interface to the Leap Motion Controller.
- *
- * Create an instance of this Controller class to access frames of tracking data
- * and configuration information. Frame data can be polled at any time using the
- * [Controller.frame]{@link Leap.Controller#frame}() function. Call frame() or frame(0) to get the most recent
- * frame. Set the history parameter to a positive integer to access previous frames.
- * A controller stores up to 60 frames in its frame history.
- *
- * Polling is an appropriate strategy for applications which already have an
- * intrinsic update loop, such as a game.
- *
- * loopWhileDisconnected defaults to true, and maintains a 60FPS frame rate even when Leap Motion is not streaming
- * data at that rate (such as no hands in frame).  This is important for VR/WebGL apps which rely on rendering for
- * regular visual updates, including from other input devices.  Flipping this to false should be considered an
- * optimization for very specific use-cases.
- *

- * @param {String} name The name of the plugin (usually camelCase).
- * @param {function} factory A factory method which will return an instance of a plugin.
- * The factory receives an optional hash of options, passed in via controller.use.
- *
- * Valid keys for the object include frame, hand, finger, tool, and pointable.  The value
- * of each key can be either a function or an object.  If given a function, that function
- * will be called once for every instance of the object, with that instance injected as an
- * argument.  This allows decoration of objects with additional data:
- *
- * ```javascript
- * Leap.Controller.plugin('testPlugin', function(options){
- *   return {
- *     frame: function(frame){
- *       frame.foo = 'bar';
- *     }
- *   }
- * });
- * ```
- *
- * When hand is used, the callback is called for every hand in `frame.hands`.  Note that
- * hand objects are recreated with every new frame, so that data saved on the hand will not
- * persist.
- *
- * ```javascript
- * Leap.Controller.plugin('testPlugin', function(){

- *     hand: function(hand){
- *       console.log('testPlugin running on hand ' + hand.id);
- *     }
- *   }
- * });
- * ```
- *
- * A factory can return an object to add custom functionality to Frames, Hands, or Pointables.
- * The methods are added directly to the object's prototype.  Finger and Tool cannot be used here, Pointable
- * must be used instead.
- * This is encouraged for calculations which may not be necessary on every frame.
- * Memoization is also encouraged, for cases where the method may be called many times per frame by the application.
- *
- * ```javascript
- * // This plugin allows hand.usefulData() to be called later.
- * Leap.Controller.plugin('testPlugin', function(){
- *   return {
- *     hand: {
- *       usefulData: function(){
- *         console.log('usefulData on hand', this.id);
- *         // memoize the results on to the hand, preventing repeat work:

- *         return this.x;
- *       }
- *     }
- *   }
- * });
- *
- * Note that the factory pattern allows encapsulation for every plugin instance.

- * ```javascript

+ * and configuration information. Frame data can be polled at any time using the
+ * [Controller.frame]{@link Leap.Controller#frame}() function. Call frame() or frame(0) to get the most recent
+ * frame. Set the history parameter to a positive integer to access previous frames.
+ * A controller stores up to 60 frames in its frame history.

+ * Polling is an appropriate strategy for applications which already have an
+ * intrinsic update loop, such as a game.
+ *
+ * loopWhileDisconnected defaults to true, and maintains a 60FPS frame rate even when Leap Motion is not streaming

+/*
+ * Registers a plugin, making is accessible to controller.use later on.
+ *
+ * @member plugin
+ * @memberof Leap.Controller.prototype
+ * @param {String} name The name of the plugin (usually camelCase).
+ * @param {function} factory A factory method which will return an instance of a plugin.
+ * The factory receives an optional hash of options, passed in via controller.use.
+ *
+ * Valid keys for the object include frame, hand, finger, and pointable.  The value
+ * of each key can be either a function or an object.  If given a function, that function
+ * will be called once for every instance of the object, with that instance injected as an
+ * argument.  This allows decoration of objects with additional data:
+ *
+ * ```javascript
+ * Leap.Controller.plugin('testPlugin', function(options){
+ *   return {
+ *     frame: function(frame){
+ *       frame.foo = 'bar';
+ *     }
+ *   }
+ * });
+ * ```
+ *
+ * When hand is used, the callback is called for every hand in `frame.hands`.  Note that
+ * hand objects are recreated with every new frame, so that data saved on the hand will not
+ * persist.
+ *
+ * ```javascript
+ * Leap.Controller.plugin('testPlugin', function(){
+ *   return {
+ *     hand: function(hand){
+ *       console.log('testPlugin running on hand ' + hand.id);
+ *     }
+ *   }
+ * });
+ * ```
+ *
+ * A factory can return an object to add custom functionality to Frames, Hands, or Pointables.
+ * The methods are added directly to the object's prototype.  Finger cannot be used here, Pointable
+ * must be used instead.
+ * This is encouraged for calculations which may not be necessary on every frame.
+ * Memoization is also encouraged, for cases where the method may be called many times per frame by the application.
+ *
+ * ```javascript
+ * // This plugin allows hand.usefulData() to be called later.
+ * Leap.Controller.plugin('testPlugin', function(){
+ *   return {
+ *     hand: {
+ *       usefulData: function(){
+ *         console.log('usefulData on hand', this.id);
+ *         // memoize the results on to the hand, preventing repeat work:
+ *         this.x || this.x = someExpensiveCalculation();
+ *         return this.x;
+ *       }
+ *     }
+ *   }
+ * });
+ *
+ * Note that the factory pattern allows encapsulation for every plugin instance.
+ *
+ * ```javascript
+ * Leap.Controller.plugin('testPlugin', function(options){
+ *   options || options = {}
+ *   options.center || options.center = [0,0,0]
+ *
+ *   privatePrintingMethod = function(){
+ *     console.log('privatePrintingMethod - options', options);
+ *   }
+ *
+ *   return {
+ *     pointable: {
+ *       publicPrintingMethod: function(){

+ * @class Controller
+ * @memberof Leap
+ * @classdesc
+ * The Controller class is your main interface to the Leap Motion Controller.
+ *
+ * Create an instance of this Controller class to access frames of tracking data
+ * and configuration information. Frame data can be polled at any time using the
+ * [Controller.frame]{@link Leap.Controller#frame}() function. Call frame() or frame(0) to get the most recent
+ * frame. Set the history parameter to a positive integer to access previous frames.
+ * A controller stores up to 60 frames in its frame history.
+ *
+ * Polling is an appropriate strategy for applications which already have an
+ * intrinsic update loop, such as a game.
+ *
+ * loopWhileDisconnected defaults to true, and maintains a 60FPS frame rate even when Leap Motion is not streaming
+ * data at that rate (such as no hands in frame).  This is important for VR/WebGL apps which rely on rendering for
+ * regular visual updates, including from other input devices.  Flipping this to false should be considered an
+ * optimization for very specific use-cases.

+ *
+ * A factory can return an object to add custom functionality to Frames, Hands, or Pointables.
+ * The methods are added directly to the object's prototype.  Finger cannot be used here, Pointable
+ * must be used instead.
+ * This is encouraged for calculations which may not be necessary on every frame.
+ * Memoization is also encouraged, for cases where the method may be called many times per frame by the application.
+ *
+ * ```javascript
+ * // This plugin allows hand.usefulData() to be called later.
+ * Leap.Controller.plugin('testPlugin', function(){
+ *   return {

-/**
- * Constructs a Controller object.
- *
- * When creating a Controller object, you may optionally pass in options
- * to set the host , set the port, or select the frame event type.
- *
- * ```javascript
- * var controller = new Leap.Controller({
- *   host: '127.0.0.1',
- *   port: 6437,
- *   frameEventName: 'animationFrame'
- * });
- * ```
- *
- * @class Controller
- * @memberof Leap
- * @classdesc
- * The Controller class is your main interface to the Leap Motion Controller.
- *
- * Create an instance of this Controller class to access frames of tracking data
- * and configuration information. Frame data can be polled at any time using the
- * [Controller.frame]{@link Leap.Controller#frame}() function. Call frame() or frame(0) to get the most recent
- * frame. Set the history parameter to a positive integer to access previous frames.
- * A controller stores up to 60 frames in its frame history.
- *
- * Polling is an appropriate strategy for applications which already have an
- * intrinsic update loop, such as a game.
- *
- * loopWhileDisconnected defaults to true, and maintains a 60FPS frame rate even when Leap Motion is not streaming
- * data at that rate (such as no hands in frame).  This is important for VR/WebGL apps which rely on rendering for
- * regular visual updates, including from other input devices.  Flipping this to false should be considered an
- * optimization for very specific use-cases.
- *

-/*
- * Registers a plugin, making is accessible to controller.use later on.
- *
- * @member plugin
- * @memberof Leap.Controller.prototype
- * @param {String} name The name of the plugin (usually camelCase).
- * @param {function} factory A factory method which will return an instance of a plugin.
- * The factory receives an optional hash of options, passed in via controller.use.
- *
- * Valid keys for the object include frame, hand, finger, and pointable.  The value
- * of each key can be either a function or an object.  If given a function, that function
- * will be called once for every instance of the object, with that instance injected as an
- * argument.  This allows decoration of objects with additional data:
- *
- * ```javascript
- * Leap.Controller.plugin('testPlugin', function(options){
- *   return {
- *     frame: function(frame){
- *       frame.foo = 'bar';
- *     }
- *   }
- * });
- * ```
- *
- * When hand is used, the callback is called for every hand in `frame.hands`.  Note that
- * hand objects are recreated with every new frame, so that data saved on the hand will not
- * persist.
- *
- * ```javascript
- * Leap.Controller.plugin('testPlugin', function(){
- *   return {
- *     hand: function(hand){
- *       console.log('testPlugin running on hand ' + hand.id);
- *     }
- *   }
- * });
- * ```
- *
- * A factory can return an object to add custom functionality to Frames, Hands, or Pointables.
- * The methods are added directly to the object's prototype.  Finger cannot be used here, Pointable
- * must be used instead.
- * This is encouraged for calculations which may not be necessary on every frame.
- * Memoization is also encouraged, for cases where the method may be called many times per frame by the application.
- *
- * ```javascript
- * // This plugin allows hand.usefulData() to be called later.
- * Leap.Controller.plugin('testPlugin', function(){
- *   return {
- *     hand: {
- *       usefulData: function(){
- *         console.log('usefulData on hand', this.id);
- *         // memoize the results on to the hand, preventing repeat work:
- *         this.x || this.x = someExpensiveCalculation();
- *         return this.x;
- *       }
- *     }
- *   }
- * });
- *
- * Note that the factory pattern allows encapsulation for every plugin instance.
- *
- * ```javascript
- * Leap.Controller.plugin('testPlugin', function(options){
- *   options || options = {}
- *   options.center || options.center = [0,0,0]
- *
- *   privatePrintingMethod = function(){
- *     console.log('privatePrintingMethod - options', options);
- *   }
- *
- *   return {
- *     pointable: {
- *       publicPrintingMethod: function(){
- *         privatePrintingMethod();
- *       }
- *     }
