 - Implement special combine options for --stable
 - Add instructions in sm-protocol for patching combine and running fits
 - Modify src/MultidimFit.cc to catch some cases where extra added points

 - Updates to the plotting layout files
template morphing for e-mu 7TeV missing signal mass point was looking for the wrong templates in some categories

adding option to switch to mvis inputs
renaming copied mvis file correctly so rest of script will work
several updates for plot cosmetics
small fix so that running without --mvis doesnt break for vhtt
