Use angular form validation

[alechenninger]

This might help clean up some of the ugliness talked about in #9. That is, use some combination of angular parsers, formatters, and validators to take care of the "intermediate" state where the model is invalid.

JSON schema can even be validated directly against lightblue's request schemas

From http://json-schema.org/implementations.html, these library's could be used to validate the schema

• http://geraintluff.github.io/tv4/
• https://github.com/natesilva/jayschema
• https://github.com/zaggino/z-schema
• https://github.com/acornejo/jjv

Lightblue data request schemas:

It might be nice to request the schemas from the lightblue instance, rather than hardcode them inside the app. See: https://github.com/lightblue-platform/lightblue-core/issues/210
