Add more comparisons

Recently I have found this library: https://github.com/jmdobry/angular-data

And I'm familiar with this fine library: https://github.com/brettshollenberger/the-abstractions-are-leaking

These would be worthy additions to your comparison section in the readme.

Wow, both libraries looks awesome and very complete.. I must say that the-abstractions-are-leaking lib made me a little envious, the lib structure is awesome, very nicely written.. I also liked the docs for both, maybe a wiki would work better for restmod than a reference page.
