Wjelement++

Hi Guys,

I’m almost done with a lightweight C++ JSON schema draft-04 wrapper around wjelement (https://github.com/petehug/wjelement-cpp). I didn’t use your own schema implementation because I need some extra features:

•	Binding of elements with validator elements
•	Storing extra details for validator nodes
•	Schema caching

Changes to wjelement I made are:

•	Add WJR_TYPE_INTEGER 
•	extra usr pointer in WJElementPublic

I was wondering if you had already planned to add WJR_TYPE_INTEGER support for schemas? If not, are there any test cases I should run to verify that my changes have no adverse effects?

Cheers
Pete
