Add some IDPVM grid helper scripts
This MR adds two useful (imo) scripts:
-
gridIPVM.py
which takes --inDS / --outDS / --nFiles (to be passed to pathena) & constructs a trf with runIDPVM.py, passing it the rest of the arguments -
mergeIDPVM.py
which runs hadd & then the IDPVM post-processing binary. Used bygridIDPVM.py
to setup output merging.
