claim call and REST documentation

LL-14:  Modified CAD API to accept a small JSON object (included in
reosurces folder of workspace) containing info about a Unit/Crew which
is used to claim a call for that crew.  Added a UnitInfo class which is
the return transformer class which the JSON is put through.  Added
AssignInfo component which grabs the CAD the crew is looking to claim
and updates the data using the fields in UnitInfo.

LL-5:  Documented all CAD REST services created thus far, saved in both
OpenOffice and MicrosoftOffice file types.
