Pull Request for Issue660: Acquaman Beam dump/fill handling

This currently has the prototype version of AM/CLSStorageRing implementations and has been implemented for VESPERS.  @davidChevrier, can you check this over for me?  Specifically the logic for beamAvailable.  @epengr, if this looks good to you, I'll add it to REIXS and IDEAS.  I'll also add it to SGM, because, why not?
Sure.
