* Objects of this class represent one specific version of a given browser. Predefined
* constants are provided for common browser versions.
*
* You can change the constants by something like:
*
* String applicationName = "APPNAME";
* String applicationVersion = "APPVERSION";
* String userAgent = "USERAGENT";
* int browserVersionNumeric = NUMERIC;
*
* BrowserVersion browser = new BrowserVersion(applicationName, applicationVersion, userAgent, browserVersionNumeric) {

* // change features here
* return BrowserVersion.BROWSER.hasFeature(property);
* }
* };
*
*
* However, note that the constants are not enough to fully customize the browser,
* you also need to look into the {@link BrowserVersionFeatures} and the classes inside "javascript" package.
