Filename of 3 clases renamed

Hi Green, 

I am just making my first contribution ever in opensource :)
I am not sure if you make this on purpose, but the clases inside
com.greenlaw110.rythm.internal.parser.toString.*
started lowercase whereas the class name was Camel case as regular.

I ate my 3 maven books and 1 git book to understand how to reach this point and make a contribution.
Note that I am getting use to some of these tooling, but I am programing for a couple of years now.
I am making a small library to have a similar Play! programming style inside java web containers. And I plan to use your template engine for it.

Hope you are doing well!
