* }
*
* The class is an updated version of Chris Schuld's Browser class version 1.9 which is unmaintained since August 20th,
* 2010. Chris' class was based on the original work from Gary White.
*
* Updates:
*
* 2016-02-11: Version 2.3.0
* + WARNING! Breaking change: public method getBrowser() is renamed to getName().
* + WARNING! Breaking change: changed the compareVersions() return values to be more in line with other libraries.
* + You can now get the exact platform version (name or version numbers) on which the browser is run on with
* getPlatformVersion(). Only working with Windows operating systems at the moment.
* + You can now determine if the browser is executed from a 64-bit platform with is64bitPlatform().
* + Better detection of mobile platform for Googlebot.
*
* 2016-01-04: Version 2.2.0
* + Added support for Microsoft Edge.
*
* 2014-12-30: Version 2.1.2
* + Better detection of Opera.
*
* 2014-07-11: Version 2.1.1
* + Better detection of mobile devices and platforms.
*
* 2014-06-04: Version 2.1
* + Added support for IE 11+.
*
* 2013-05-27: Version 2.0 which is (almost) a complete rewrite based on Chris Schuld's Browser class version 1.9 plus
* changes below.
* + Added support for Opera Mobile
* + Added support for the Windows Phone (formerly Windows Mobile) platform
* + Added support for BlackBerry Tablet OS and BlackBerry 10
* + Added support for the Symbian platform
* + Added support for Bingbot
* + Added support for the Yahoo! Multimedia crawler
* + Removed iPhone/iPad/iPod browsers since there are not browsers but platforms - test them with getPlatform()
* + Removed support for Shiretoko (Firefox 3.5 alpha/beta) and MSN Browser
* + Merged Nokia and Nokia S60
* + Updated some deprecated browser names
* + Many public methods are now protected
* + Documentation updated
*
* 2010-07-04:
* + Added detection of IE compatibility view - test with getIECompatibilityView()
* + Added support for all (deprecated) Netscape versions
* + Added support for Safari < 3.0
* + Better Firefox version parsing
* + Better Opera version parsing
* + Better Mozilla detection
