/**
* The BrowserDetection class facilitates the identification of the user's environment such as Web browser, version,
* platform and device type.
*
* Typical usage:
*
* $browser = new Wolfcast\BrowserDetection();
* if ($browser->getName() == Wolfcast\BrowserDetection::BROWSER_FIREFOX &&
* $browser->compareVersions($browser->getVersion(), '5.0') >= 0) {
* echo 'You are using FireFox version 5 or greater.';
* }
*
* The class is a rewrite of Chris Schuld's Browser class version 1.9 which is mostly unmaintained since August 20th,
* 2010. Chris' class was based on the original work from Gary White.
*
* Updates:
*
* 2019-03-27: Version 2.9.3
* + Fixed Edge detection on Android.
* + Added Android Q detection.
* + Now filtering superglobals.
*
* 2019-02-28: Version 2.9.2
* + Fixed Opera detection.
*
* 2018-08-23: Version 2.9.1
* + Fixed Chrome detection under iOS.
* + Added Android Pie detection.
* + Added macOS Mojave detection.
*
* 2018-07-15: Version 2.9.0
* + WARNING! Breaking change: new Wolfcast namespace. Use new Wolfcast\BrowserDetection().
* + iPad, iPhone and iPod are all under iOS now.
* + Added Android Oreo detection.
* + Added macOS High Sierra detection.
* + Added UC Browser detection.
* + Improved regular expressions (even less false positives).
* + Removed AOL detection.
* + Removed the following Web browsers detection: Amaya, Galeon, NetPositive, OmniWeb, Vivaldi detection (use
* addCustomBrowserDetection()).
* + Removed the following legacy platforms detection: BeOS, OS/2, SunOS (use addCustomPlatformDetection()).
*
* 2016-11-28: Version 2.5.1
* + Better detection of 64-bit platforms.
*
* 2016-08-19: Version 2.5.0
* + Platform version and platform version name are now supported for Mac.
* + Fixed platform version name for Android.
*
* 2016-08-02: Version 2.4.0
* + Platform version and platform version name are now supported for Android.
* + Added support for the Samsung Internet browser.
* + Added support for the Vivaldi browser.
* + Better support for legacy Windows versions.
*
* 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 2.1.0
* + Added support for IE 11+.
*
* 2013-05-27: Version 2.0.0 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
