+
+Changelog:
+2010.09.06 - 0.7-beta1
+  - features: vsprintf, support for named placeholders
+  - enhancements: format cache, reduced global namespace pollution
+
+2010.05.22 - 0.6:
+ - reverted to 0.4 and fixed the bug regarding the sign of the number 0
+ Note:
+ Thanks to Raphael Pigulla <raph (at] n3rd [dot) org> (http://www.n3rd.org/)
+ who warned me about a bug in 0.5, I discovered that the last update was
+ a regress. I appologize for that.
+
+2010.05.09 - 0.5:
+ - bug fix: 0 is now preceeded with a + sign
+ - bug fix: the sign was not at the right position on padded results (Kamal Abdali)
+ - switched from GPL to BSD license
+
+2007.10.21 - 0.4:
+ - unit test and patch (David Baird)
+
+2007.09.17 - 0.3:
+ - bug fix: no longer throws exception on empty paramenters (Hans Pufal)
+
+2007.09.11 - 0.2:
+ - feature: added argument swapping
+
+2007.04.03 - 0.1:
+ - initial release

+     * has methods which take the line segment length as an argument
+     * and return the computed final position.
+     *
+     * There are two different position-calcuating methods,
+     * corresponding to two different interpretations of the relative
+     * value `a`:
+     *
+     * **relative length**:
+     *     `a` is a number between 0 and 1, representing a fraction of
+     *       the total length of the line segment; the relative
+     *       position determined by `a` is the fraction `a` of the
+     *       total length of the segment.
+     *     In this case, the position-calculating method
+     *       `calculateLength(L)` returns the number `a * L + b`, which
+     *       corresponds to moving `a` of the way along the length L,

+     *             |<------------------  L  -------------------->|
+     *
+     * **relative coordinate**:
+     *     `a` is a number between -1 and 1, representing a coordinate
+     *       value in a [-1,1] coordinate system along the line
+     *       segment.
+     *     In this case, the position-calculating method

+     *       b`.  which corresponds to moving to the position

+         * EventEmitter is a Jermaine model that supports basic event emitting /
+         * handling for Jermaine objects.
+         *
+         * Events are represented as plain old JavaScript objects with at least
+         * the following two properties:
+         *
+         *   **type**
+         *
+         *   > a string giving the type of the event; this can be any
+         *     arbitrary string.  The event type is not restricted to be
+         *     from some predetermined list; applications are free to
+         *     use whatever strings they want for their event types.
+         *
+         *   **target**
+         *
+         *   > a reference to the object that emitted the event
+         *
+         * Event objects may also contain arbitrary other properties that are specific to
+         * a particular event type.
+         *
+         * Any Jermaine model can declare itself to be an event emitter by saying
+         * "this.isA(EventEmitter)" in its model declaration.
+         *
+         * This adds three methods to the model:
+         *  
+         *   **addListener(eventType, listenerFunction)**
+         *
+         *   > Registers listenerFunction as a listener for events of type
+         *     eventType (a string).  listenerFunction should be a function
+         *     that accepts a single argument which will be a reference to an
+         *     event object as described above.  When the object emits the
+         *     event, the listener function will be invoked in the context
+         *     where its "this" keyword refers to the object that emitted the
+         *     event (the event target).  If listenerFunction is already
+         *     registered as a listener for eventType, this function does
+         *     nothing --- each listener function can be registered only once.
+         *
+         *   **removeListener(eventType, listenerFunction)**
+         *
+         *   > Removes the given listenerFunction from the list of listeners
+         *     for this object for events of type eventType.
+         *
+         *   **emit(event)**
+         *
+         *   > Causes the object to emit the given event.  The argument can be
+         *     either a string, in which case it is assumed to be an event type
+         *     and is converted to an event object with the given 'type'
+         *     property, or an event object with a 'type' property and any
+         *     other desired properties.  The emit() method automatically adds
+         *     a 'target' property to the event object, whose value is a
+         *     reference to the object emitting the event.
+         *
+         * In most cases the emit() method is only called from within the
+         * implementation of an EventEmitter object, and code external to the
+         * object's model will use its addListener() and removeListener() methods
+         * to process events that the object emits.  All three of these methods
+         * are public methods, though, so it's also possible for code outside of
+         * an object's implementation to cause it to emit an event, or for the
+         * object's own code to listen for and process its own events.
+         *
+         * Two special types of events are always present for every EventEmitter
+         * object: the "listenerAdded" and "listenerRemoved" events.  These
+         * events make it possible to monitor the addition or removal of event
+         * listeners.  The "listenerAdded" event is emitted whenever a new
+         * listener function is added, and the "listenerRemoved" event is emitted
+         * whenever a listener is removed.  Each of these events contain the
+         * following properties:
+         *
+         *   **targetType**
+         *
+         *   > the event type associated with the listener
+         *     being added or removed
+         *
+         *   **listener**
+         *
+         *   > the listener function being added or removed
+         *
+         * @class EventEmitter

+//                           default) means don't draw outlines.

+     * The "covered" range is the interval of the data number line for
+     * which this node is responsible for storing data; Multigraph
+     * uses range this to avoid requesting the same data twice --- it
+     * never requests data for a range already covered by an existing
+     * cache node.
+     * 
+     * Initially, when the WebServiceDataCacheNode is created, the
+     * limits of the covered range are specified in the constructor.
+     * Later on, when the node's data is actually populated, the
+     * limits are potentially adjusted outward, if the range of data
+     * received is larger than the initially specified covered range.
+     * So in all cases, the covered range indicates the range for
+     * which no more data is needed, because it's covered by this
+     * node.
+     * 
+     * Note that the covered range is never adjusted to be smaller.
+     * 
+     * The WebServiceDataCacheNode does not actually fetch any data
+     * --- it is simply a storage container for fetched data; it's up
+     * to other code outside of this object to fetch and populate the
+     * data.

+        // the outlines around the bars, in order to make sure that it only draws
+        // one vertical line between two bars that share an edge.  If a complete
+        // outline were drawn around each bar separately, the common edge between
+        // adjacent bars would get drawn twice, once for each bar, possibly in
+        // slightly different locations on the screen due to roundoff error,
+        // thereby making some of the outline lines appear thicker than others.
+        // 
+        // In order to avoid this roundoff artifact, this render only draws the
+        // bars (the filled region of the bar, that is) in its dataPoint() method,
+        // and keeps a record of the bar locations and heights so that it can draw all
+        // of the bar outlines at once, in its end() method.  The bar locations and
+        // heights are stored in an array called _barGroups, which is an array of
+        // "bar group" objects.  Each "bar group" corresponds to a sequence of adjacent
+        // bars --- two bars are considered to be adjacent if the right edge of the left
+        // bar is within _pixelEdgeTolerance pixels of the left edge of the right bar.
+        // A "bar group" is represented by an array of points representing the pixel
+        // coordinates of the upper left corners of all the bars in the group, followed by
+        // the pixel coordinates of the upper right corner of the right-most bar in the group.
+        // (The last, right-most, bar is the only one whose upper right corner is included
+        // in the list).  So, for example, the following bar group
+        // 
+        //        *--*
+        //        |  |--*
