/**
 * Browsers' descriptors
 *
 * The idea of descriptors is simple. You should know about them two simple things:
 * 1. Every descriptor has a method or property called `test` and a `describe` method.
 * 2. Order of descriptors is important.
 *
 * More details:
 * 1. Method or property `test` serves as a way to detect whether the UA string
 * matches some certain browser or not. The `describe` method helps to make a result
 * object with params that show some browser-specific things: name, version, etc.
 * 2. Order of descriptors is important because a Parser goes through them one by one
 * in course. For example, if you insert Chrome's descriptor as the first one,
 * more then a half of browsers will be described as Chrome, because they will pass
 * the Chrome descriptor's test.
 *
 * Descriptor's `test` could be a property with an array of RegExps, where every RegExp
 * will be applied to a UA string to test it whether it matches or not.
 * If a descriptor has two or more regexps in the `test` array it tests them one by one
 * with a logical sum operation. Parser stops if it has found any RegExp that matches the UA.
 *
 * Or `test` could be a method. In that case it gets a Parser instance and should
 * return true/false to get the Parser know if this browser descriptor matches the UA or not.
