/**
* 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.
