New: multiforcing is enabled
New: add unitests to the multiforcing implementation
Fix: ticket:371
For such purpose:
Define a text file with a name somefile.list. Make sure it finishes with ".list":
forcing_file1.nc
forcing_file2.nc
forcing_file3.nc
forcing_file4.nc
In the run.def:
FORCING_FILE=somefile.list -> enable multiforcing
FORCING_FILE=someforcing.nc -> disable multiforcing (normal use)
Optional flag:
FORCING_CYCLE=y/n to iterate over them (e.g: spinup)
