// BETA NOTICE
// Previous versions of the JavaScript code for MobileESP were 'regular' 
// JavaScript. The strength of it was that it was really easy to code and use.
// Unfortunately, regular JavaScript means that all variables and functions
// are in the global namespace. There can be collisions with other code libraries
// which may have similar variable or function names. Collisions cause bugs as each
// library changes a variable's definition or functionality unexpectedly.
// As a result, we thought it wise to switch to an "object oriented" style of code.
// This 'literal notation' technique keeps all MobileESP variables and functions fully self-contained.
// It avoids potential for collisions with other JavaScript libraries.
// This technique allows the developer continued access to any desired function or property.
//
// Please send feedback to project founder Anthony Hand: anthony.hand@gmail.com
//
//
// 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. 
//	- Reorganized DetectMobileQuick(). Moved the following to DetectMobileLong():
//		- DetectDangerHiptop(), DetectMaemoTablet(), DetectSonyMylo(), DetectArchos()
//
