Lots more cleanup and coverage testing:
 - Remove resolveSources/Tests/etc and replace with more general resolveGlobs function, that takes options to allow searching globs on custom objects, by namespace'd scope string.
 - Move the application CLI logic into bin/ezc to separate from library logic.
 - Add tests for util.js, and update context tests to reflect api changes.
 - Clean up test fixture duplication for context tests
