Update README

Adding some more information. 

I have given a brief explanation of the gem and a loose timeline.
This is to let people know whats going on here if they do come 
across the repo before there is any working code. 

Once there is a fully functional iteration I intend to cultivate
community interest by sharing development goals and welcoming
outside participation.

For me this is a tool that I would like to have for my own use
but I think that there may be other projects could use something
like this.
