1) added ,'r' when a NetCDF file is read.
2) result=close(nc)  --> close(nc)
3) Commented redef(nc)/endef(nc). It crashes Octave and seems is not mandatory for Matlab

4) Added swicth  isoctave for "major" changes. See make_grid for an example where it prevents running make_coast, since it not adapted yet for Octave.
