starting commit for the Hammer parsing library

attempting to add a formula for hammer 
https://github.com/UpstandingHackers/hammer/blob/master/README.md

brew has been tested on mavericks with dependancies as is but their might be some other deps I missed. If they are missing though they can be added from home-brew since thats what I used to install the libs on my test machine that I used to test the build.

Also I have never submitted a pull request to a public project OR written a brew formula before, so I'm sure I did some kinda dumb crap, feel fee to yell at me so I can fix it.
