Port of AsFac ( https://github.com/thedevstop/asfac ) to TypeScript. Greatly simplified since there is no reflection in TypeScript. Passes no parameters when invoking a constructor and does not perform property injection.

Removed JS output

Constructor functions are separated from callback functions since we expect callback functions to take 2 parameters (JsFactory and ScopeName). Ported over the applicable AsFac tests.
