- Updated the managers documentation a little

- The  crystal settings calculation in hkl now tried to put omega into
  the limts by calculating a delta omega.
- TRICS data files now include HKL and the UB
- The scan module has been expanded to support user defined scans which
  run a script at any scan point.
- A small fix to the PSD code in SinqHM_srv_filler
