%
%  This sofware permit to visualize output files from the 
%  HOPS model. The present sofware scan which variables can 
%  visualized form the output file. All the information is read
%  form the .nc file, so any additional information is needed
% 
%  All the subroutines are well documented, please refear to them 
%  in case of any problem
%  
%  The main subroutines are
%
%
%
%  hopsgui			- VISUALIZATION TOOL FOR HOPS NETCDF FILES, MAIN program.
