// Copyright 2010-2015, Anthony Hand
//
//
// File version 2015.05.13 (May 13, 2015)
// Updates:
//	- Moved MobileESP to GitHub. https://github.com/ahand/mobileesp
//	- Opera Mobile/Mini browser has the same UA string on multiple platforms and doesn't differentiate phone vs. tablet. 
//		- Removed DetectOperaAndroidPhone(). This method is no longer reliable. 
//		- Removed DetectOperaAndroidTablet(). This method is no longer reliable. 
//	- Added support for Windows Phone 10: variable and DetectWindowsPhone10()
//	- Updated DetectWindowsPhone() to include WP10. 
//	- Added support for Firefox OS.  
//		- A variable plus DetectFirefoxOS(), DetectFirefoxOSPhone(), DetectFirefoxOSTablet()
//		- NOTE: Firefox doesn't add UA tokens to definitively identify Firefox OS vs. their browsers on other mobile platforms.
//	- Added support for Sailfish OS. Not enough info to add a tablet detection method at this time. 
//		- A variable plus DetectSailfish(), DetectSailfishPhone()
//	- Added support for Ubuntu Mobile OS. 
//		- DetectUbuntu(), DetectUbuntuPhone(), DetectUbuntuTablet()
//	- Added support for 2 smart TV OSes. They lack browsers but do have WebViews for use by HTML apps. 
//		- One variable for Samsung Tizen TVs, plus DetectTizenTV()
//		- One variable for LG WebOS TVs, plus DetectWebOSTV()
//	- Updated DetectTizen(). Now tests for "mobile" to disambiguate from Samsung Smart TVs
//	- Removed variables for obsolete devices: deviceHtcFlyer, deviceXoom.
//	- Updated DetectAndroid(). No longer has a special test case for the HTC Flyer tablet. 
//	- Updated DetectAndroidPhone(). 
//		- Updated internal detection code for Android. 
//		- No longer has a special test case for the HTC Flyer tablet. 
//		- Checks against DetectOperaMobile() on Android and reports here if relevant. 
//	- Updated DetectAndroidTablet(). 
//		- No longer has a special test case for the HTC Flyer tablet. 
//		- Checks against DetectOperaMobile() on Android to exclude it from here.
//	- DetectMeego(): Changed definition for this method. Now detects any Meego OS device, not just phones. 
//	- DetectMeegoPhone(): NEW. For Meego phones. Ought to detect Opera browsers on Meego, as well.  
//	- DetectTierIphone(): Added support for phones running Sailfish, Ubuntu and Firefox Mobile. 
//	- DetectTierTablet(): Added support for tablets running Ubuntu and Firefox Mobile. 
//	- DetectSmartphone(): Added support for Meego phones. 
//	- Refactored the detection logic in DetectMobileQuick() and DetectMobileLong().
//		- Moved a few detection tests for older browsers to Long.

 * The DetectSmartPhone class encapsulates information about

 *   You can use it to find out whether the browser asking for
 *   your site's content is probably running on a mobile device.
 *   The methods were written so you can be as granular as you want.
 *   For example, enquiring whether it's as specific as an iPod Touch or
 *   as general as a smartphone class device.
 *   The object's methods return true, or false.
