Thank you @MohitS704 , it's great to have this ready!

I have added some comments of a few details that need to be fixed.
Also, as I mentioned ADD_LHE_PROB must be True to have LHE angles computed; given that this is mandatory when APPLY_K_NNLOQCD_ZZGG!=False, I would suggest to automatically set it here.

@bellan : FYI; please note that once merged this will affect your samples as well. I suppose you also need it for VBS - Please let us know if you have any comment!

Note that this must be true when APPLY_K_NNLOQCD_NLOEW_ZZQQB, not APPLY_K_NNLOQCD_ZZGG. My understanding is the qqbar->ZZ samples are extremely large, so I have made it so that ADD_LHE_PROB is dependent on ADD_ALLEVENTS or APPLY_K_NNLOQCD_NLOEW_ZZQQB, so that the framework is not overburdened.

Right - I copied the wrong flag!
