Matching haloes

[VictorForouhar]

Script is intended to be used to match haloes across simulations/halo finder runs using SOAP membership files.

I have basic matching done. I still need to add an initial sorting step in ascending particle ID, to handle different versions of the same simulation box (e.g. DMO vs HYDRO and HYDRO variations). I also want to make MPI rank sorting of subhaloes to match to be ordered and continuous in value.

This is the script I am using to test the implementation (HBT to VR central subgroups)

#!/bin/bash -l

Closing due to #112. Thanks for this script though @VictorForouhar, it was very useful as a basis!
