Create MCMultiParticleMassFilter.cc

[MohitS704]

PR description:

Adding a new PYTHIA filter that checks whether the sum of all the particles (that pass a specific pt and eta cut) has a mass between the values that you set. This is based off of the idea raised in this CMS-talk post. Even though the post (and the branch name) imply that the filter is for the 4-lepton channel only, it can easily be used in other channels, as the only inputs are the PDG IDs of the particles you would like. PR validation:

I've tested the filter to see that it does in fact only let through particles with the IDs that you specify, and that it will only allow events with particles that pass the pt and eta cuts which sum to a vector that has an invariant mass between the specified maximum and minimum values.

I think I did the previous PR incorrectly. That one is linked here, and is functionally identical.

Hi, besides the comments inline, one more question: in the case of there are 3 particles pass the kinematic cuts, and you are requiring a selection on two particles, will your code consider the combination of the first and the third particle.

I realized earlier that I had neglected to include this case. This is now covered by the for loop at the end of the recurseLoop function that instantiates the recursion over the rest of the vector in the most recent commit.
