bug in my setaux fix
new flag renamed NEEDS_TO_BE_SET in geo subrs too
forgot to include this file in the change of var name
changed the ghost cell comp. in setaux to minimize roundoff too. changed comments in filpatch
fixed bug from 2 years back in reloop/divide_mass
merged mjberger/auxpar into rjleveque/auxpar, where  I had made different changes to setaux.f90 to floating point numbers along with floor parens.  Marsha changed i,j to ii,jj in commit d6dc405. Merge our changes
