Detailed Description

Empty utitlity class that handles return values of netcdf functions and throws NC_Error(status) if( status != NC_NOERR)

For example

file::NC_Error_Handle err;
int ncid = -1;
try{
     err = nc_open( "file.nc", NC_WRITE, &ncid);
//throws if for example "file.nc" does not exist
} catch ( std::exception& e)
{
     //log the error and exit
     std::cerr << "An error occured opening file.nc !\n"<<e.what()<<std::endl;
     exit( EXIT_FAILURE);
}

This allows for a C++ style error handling of netcdf errors in that the program either terminates if the NC_Error is not caught or does something graceful in a try catch statement.
