// Copyright 2010-2011, Anthony Hand
//
// File version date: August 22, 2011
//		Update: 
//		- Updated DetectAndroidTablet() to fix a bug introduced in the last fix! The true/false returns were mixed up. 
//
// File version date: August 16, 2011
//		Update: 
//		- Updated DetectAndroidTablet() to exclude Opera Mini, which was falsely reporting as running on a tablet device when on a phone.
//		- Updated the user agent (uagent) init technique to handle spiders and such with null values.
//
// File version date: August 7, 2011
//		Update: 
//		- The Opera for Android browser doesn't follow Google's recommended useragent string guidelines, so some fixes were needed.
//		- Updated DetectAndroidPhone() and DetectAndroidTablet() to properly detect devices running Opera Mobile.
//		- Created 2 new methods: DetectOperaAndroidPhone() and DetectOperaAndroidTablet(). 
//		- Updated DetectTierIphone(). Removed the call to DetectMaemoTablet(), an obsolete mobile OS.
//
// File version date: July 15, 2011
//		Update: 
//		- Refactored the variable called maemoTablet. Its new name is the more generic deviceTablet.
//		- Created the variable deviceWebOShp for HP's line of WebOS devices starting with the TouchPad tablet.
//		- Created the DetectWebOSTablet() method for HP's line of WebOS tablets starting with the TouchPad tablet.
//		- Updated the DetectTierTablet() method to also search for WebOS tablets. 
//		- Updated the DetectMaemoTablet() method to disambiguate against WebOS tablets which share some signature traits.
