This relie on Dynamic imports a New feature that was included in Typescript recently

* This code as been tested, and successfuly pass each test as excepted

* Adding test case to Print Version of the Lib

Version is populated after the Constructor call (in less than a second)
It's because of the Asynchronous Task, (It's not a real deal, because it allow the lib to Work on a Browser)
