MadGraph5_aMC@NLO 2.2.x "split and conquer"

2.2.0(24/09/14) VH: General mixed order corrections in MadLoop (only), including QCD/EW/QED and
                    the UFO@NLO model 'loop_qcd_qed_sm'.
                VH: Re-design of both the tree and MadLoop matrix elements output to compute
                    contributions of different coupling order combinations independently from one another.
                VH+HS: Tensor integral reduction as implemented in PJFry and IREGI readily available
                    and interfaced to MadLoop's output.
                VH: Re-structuring of MadLoop's standalone output so as to easily create a single dynamic
                    library including many processes at once. Useful for interfacing MadLoop to other MC's
                    and already working with Sherpa.
                VH+HS: This branch contains all the fixes for proper treatment of the latest BSM@NLO models
                    produced by FeynRules@NLO. In particular, the fixed related to the presence of majorana
                    particles in loop ME's.
                RF: Corrected the behaviour of the pdfcode parameter in the shower_card for NLO+PS runs.
                PT: Redesigned shower_card.dat and eliminated modbos options for Herwig6
                RF: Change the SPINUP information in the NLO LHEF from 0 to 9 (i.e. sum over helicities)
                RF: Fixed a bug in the check on the determination of the conflicting BWs.
                RF: Added the aMCfast+APPLgrid interface (arXiv:1406.7693 [hep-ph])
                PT: Redesigned shower_card.dat and eliminated modbos options for Herwig6
                RF: Change the SPINUP information in the NLO LHEF from 0 to 9 (i.e. sum over helicities)
                RF: Fixed a bug in the check on the determination of the conflicting BWs.
                MZ: enabled LHAPDF6 interface
                OM: Fixed a crash in some HEFT merging case.
                OM: Fix various compatibility problem created by the LHEFv3 version (Thanks to S. Brochet)
                OM: Fix a bug for MadSpin in gridpack mode
                OM: Add a routine to check the validity of LHE file (check_event command)
                OM: Fix bug for UFO model with custom propagators
                OM: Fix Bug in the computation of cross-section in presence of negative contribution
                OM: Change colorflow information of LHE file in presence of two epsilon_ijk
                    since PY8 was not able to handle such flow in that format.
                OM: Add the function print_result for aMC@(n)LO run.
                OM: Add some shortcut in the card edition
                    set ebeam 500 # edit both beams
                    set lpp 0 # edit both lpp1 and lpp2
                    set lhc 14 # configure for LHC 14TeV
                    set ilc 1000 # configure for ilc 1TeV
                    set fixed_scale 100 # set all scale to fixed and at 100GeV
                    set showerkt T # set showerkt on T in the shower card
                    set qcut 20 # set the qctu to 20 in the shower card
                OM: Fix a bug in the card edition mode which was sometimes returning to default value
                    which were edited by hand and not via the set command.
                Seoyoung Kim (by OM): Implementation of the htcaas (super-)cluster support.
                Juan Rojo (by RF): extended the 3 internal NNPDF sets for scales relevant for a 100TeV collider.
                OM: Fix a problem with the creation of DJR plot with root 6
                OM: allow the set the width to Auto in NLO computation (width computated at LO accuracy)
                OM: Adding the possibility to have automatic plot after the parton shower for Herwig6/Pythia6.
                    This require MadAnalysis and the pythia-pgs package.
