Allow for Massive Missing Particles in TupleToolCorrectedMass

Adding a few lines to TupleToolCorrectedMass so that missing particles with mass can be included in mass reconstructions. This is for an analysis of Lb -> LcLc~n where we are considering the neutron a missing particle. Unless explicitly stated the mass of the invisible particle is by default 0 and the TupleTool acts as it was previously, so users do not have to specify M_invis = 0.

Adding lines like this in the options file will result in non 0 invisible mass.

dtt.addTupleTool("TupleToolCorrectedMass/M_n")
dtt.M_n.MassInvisible = 939.56542052 * MeV

Why is this going towards 2018-patches?

I already exchanged with @nhowarth that it should go to run2-patches. Probably good to later cherry-pick to the other branches, though.

@nhowarth 2018-patches and run2-patches have diverged considerably. You will need to create a new branch from run2-patches and make a new MR

no problem, will do.

Thanks @nhowarth. Note that members should be m_XXX, so m_invis rather than M_invis. I would write m_invisible.

changed target branch from 2018-patches to run2-patches

Are you sure this won't affect the uncertainty calculation?
