NEON-1062 Stubbing out the filter builder directive files.
Merge branch 'angular-demo' of https://github.com/NextCenturyCorporation/neon into angular-demo
NEON-1060 Correcting some typos.
NEON-1057 Correcting a minor bug where the queryForData() function was used both as a private function and a scope function.  I consolidated its use as a scope function.
NEON-1062 Filling in the initial filtering capability.  It's enough to create and remove some basic AND filters and includes some neon extensions from the previous widget.  More UX logic and module cleanup to ensue.
