Fix the way the number of node strings is calculated to work on older MATLAB versions (specifically v2010a).
Included a stride option in the time_idx in read_netCDF_fvcom.m. You can now select all date_range in the netcdf file (date_range=-1) but subsample the variables at read time rather than afterwards. I have also coded the option to limit three dimensions simultaneously. Previously only two dimensions were allowed.
Fix typo.
Merge new functionality from Riqui to allow subsetting in all of space (horizontal and vertical) and time together.
