updated code:
RDMFT loop interfaced with ED_SOLVER.

the driver ed_ahm_squareRDMFT.f90 calls the actual solver
contained in the interface
RDMFT_WRAP_ED.f90

Code tested against single-site code for the homogeneous square lattice
Preliminary results are in good agreement; more rigorous tests are needed.

On DUALLA seems to be problems with parallel computations. Check!
