Add Typings for typescript

[CucumisSativus]

Hello, first of all thanks for your project, it made my life much easier.

This is a typings file i needed to put in my project in order to use ract-easy-print with my tslint configuration. Hope it will be useful. Please note i'm a javascript newbie so please do not hesitate to point my mistakes in this file.
