decouple multiple mass (multishift) solver from IO routines and generalize
add temporary CGMMS io routine to invert_eo until spinor IO is refurbished and generalized
rat, ratcor, cloverrat and cloverratcor monomials based on Barteks new cg_mms version
rational monomial for single Wilson or Clover fermion seems to be working
fix for new cgmms, I think its working now...
Merge pull request #1 from urbach/brational

single clover and Wilson rational approximation plus fix of `invert_eo.c` for cgmms
