VTS-SimPipe v2.0.0 with CORSIKA Optimizations

This is the v2.0.0 release of VTS SimPipe - a simulation pipeline for VERITAS. It includes container build scripts for all simulation steps (air shower, atmospheric transfer, ray tracing, camera simulations) and scripts to efficiently start productions (including scripts using the HTCondor DAGMAN functionality).

Simulation software versions (installed in containers):

• CORSIKA v7.7500 (optimised and non-optimised versions)
• ROOT 6.24.06 (base image centos7)
• corsikaIOreader v2.0.0
• GrOptics v4.2.2 (GM fork)
• VBF v0.3.4
• CARE v1.7.1
• mergeVBF (as part of Eventdisplay v490.5)

This release includes the optimized versions of CORSIKA with hugely improved run-time performance due to the application of vectorized code.
