Support ability to run module installed via a git url

One of the benefits is that we are not ever blocked by a release as we may choose to implement the module as it is at some commit.

I had experimented with this. I used npm script "postinstall" to compile the ts files after the module was installed via a git commit url. It worked fine for me locally. Jimmy and Nicolas had issues with it however. It didn't seem that all of the necessary files were being compiled.
