184	Big IO update, parallel synchronization	arango	arango	"This is a big update to ROMS IO.  It is part of the parallel IO that will be available in the near future.  The synchronization with '''exit_flag''' is more rigorous now to avoid having the model to hang-up during MPI computations with IO problems.

I built an umbrella over all the non-tiled NetCDF IO manipulations.  This will facilitate parallel IO and the code is much cleaner and elegant.  All the NetCDF verbose calls are located in a single place (see all new routines in '''mod_netcdf''') to read and write non-tiled variables.

I also added a generic logic for the IO of nested grids. See new '''IOBOUNDS''' structure in '''mod_param.F'''.

A new routine ('''def_dim.F''') is provided to define any NetCDF dimension with the necessary parallel logic and error checking.

I also corrected few IO bugs.

I tried to test as much as I can. However, I didn't test all the possible combinations of CPP flags."	upgrade	closed	major	Parallel Input/Output	Parallelism	3.2	Done
