Added EditRequirementPanel/Tabs
Started creating a local model which can be accessed everywhere to store requirements.
Changed showing all requirements to use the local model as a test.  It works as expected.  I'll convert the rest of them soon, and then move back to working on the edit requirement system.
Fixed an incorrect return value in EditRequirementPanel
Merge branch 'dev-feature-editreq' into dev-feature-localmodel
Completed (hopefully) transition to using local model of all requirements. All controllers successfully deal with it appropriately.  Also, added documentation to the entire LocalRequirementModels class.
