All the hooks!
--------------

Non-blocking callbacks
======================
- Scan start
   - RunStart Document created
   - EventDescriptor document created
   - Event Document created
   - RunStop Document created
   - Scan stop

Optionally-blocking callbacks
=============================
- The positioner and detector triggering hooks should execute in the same
  process as the currently running scan

- Positioner hooks
   - before move
   - during move
   - after move

- Detector triggering hooks
   - before detector triggering
   - during detector triggering
   - after detector triggering

Other magic things that should be considered
--------------------------------------------
- define conditions for "pause-scan", "recollect-datapoint"
   - This could be done by raising a "PauseScanException" or
     "RecollectDatapointException" in the callback.
