* @class Ext.Version
*
* A utility class that wrap around a string version number and provide convenient
* method to perform comparison. See also: {@link Ext.Version#compare compare}. Example:
*
* var version = new Ext.Version('1.0.2beta');
* console.log("Version is " + version); // Version is 1.0.2beta
*
* console.log(version.getMajor()); // 1
* console.log(version.getMinor()); // 0
* console.log(version.getPatch()); // 2
* console.log(version.getBuild()); // 0
* console.log(version.getRelease()); // beta
*
* console.log(version.isGreaterThan('1.0.1')); // True
* console.log(version.isGreaterThan('1.0.2alpha')); // True
* console.log(version.isGreaterThan('1.0.2RC')); // False
* console.log(version.isGreaterThan('1.0.2')); // False
* console.log(version.isLessThan('1.0.2')); // True
*
* console.log(version.match(1.0)); // True
* console.log(version.match('1.0.2')); // True
*
