Removed AMSampleStage because it will be replaced with AMMotorGroup.  AMSampleStage may return in the future, but it will be to fill a specific role.
Built the new AMMotorGroup and view.  It should effectively replace the VESPERSMotorGroup and view.  Some testing required before swapping it entirely with the VESPERSMotorGroup or for further subclassing. #461
Minor fixes to AMMotorGroupView.  VESPERS: Switched from using VESPERSMotorGroup to AMMotorGroup.
