VAMP: dump state and resume integration
| Reported by: | kilian | Owned by: | brass |

Description
While WHIZARD can catch and handle external signals, VAMP currently can't.
Intended behavior: the sampling function raises an exception, which is caught by vamp_sample_grids (etc.) to clean up and store its current state: grid file plus any extra local data. Resuming the run, there should be a way to make use of this snapshot.
Currently, the sampling function can't raise VAMP exceptions. More importantly, VAMP has no snapshots - it can store/retrieve grids, but not local integration data.

Replying to jr_reuter:
Who is supposed to do this? And when???
It's a new feature in any case, and not urgent. May discuss this in a later meeting.

VAMP can already checkpoint AFTER each iteration. Do we also want to checkpoint DURING an iteration? Then the grid structure has to augmented by the partially filled histograms and the TAORNG state.
A simple first step would be to add a checkpoint hook in the iteration loop.

Not worth the extra effort to make it work seamlessly w/MPI.
