First release of HK Hybrid / nuPRISM merge

Merge completed by Benjamin Quilain of Hyper-K Hybrid PMT and nuPRISM WCSim versions.
This is the first version, validated by Benjamin and Ryosuke Akutsu and presented at the June 2021 Hyper-Kamiokande collaboration meeting.

Release for the mPMT IWCD production

Digitized time bug fixed.
Events generated to the edge of the tank.
Generator skips initial neutrino, target nucleus and target nucleon.
Detector geometry offset changed to work with the latest NEUT vectors.

Release with neutron capture on Gadolinium

• Code for modelling neutron capture Gadolinium added.
  • Turned off by default, configurable in the macro file.
• More detail in pull request #32

Release with multi-PMT geometry

This is a significant update from the previous release. The main changes are:

• multi-PMT modules have been implemented. E61 geometries with multi-PMTs available.
• WCSim v1.7.0 was merged in. This version should be run with Geant 4.10.01.p03 and uses the FTFP_BERT physics list.
• Gadolinium doping has been included as an option, disabled by default
• The default E61 geometry has been changed to a 6m high, 8m diameter inner detector, instrumented with mPMTs

Fix X position problems with last release and add 5in and 3in PMTs

Updated release of NuPRISM/WCSim to include a few bug fixes that were used in the last production:

• Add correction for varying X position of interactions in the detector
  • NuPRISM Phase-1 is located directly above the neutrino beam, so the X position offset between the detector and the NRooTracker events was 0. Phase-0 is moved ~10m off the beam axis in the x direction, which should have been accounted for.
• Update to settings pass through tree to include information needed by fiTQun
  • This was missed in the last release by accident

Also add in 3in and 5in PMTs from Yoshida-san - these will be useful for further study before moving to latest WCSim version

First NuPRISM physics release

Patched version of nuprism-v1.0.0 that fixes the muon decay bug in WCSim. This should be used to develop the NuPRISM analysis framework.

Development of WCSim/nuPRISM for detector design studies will begin in a new branch

First production to study MC reconstruction

First release of nuPRISM/WCSim! This is going to be used to study the particle reconstruction performance, using neutrino interactions and particle guns.
