Improved error handling as NetCDF calls exit by default for errors.
Improved error handling as NetCDF calls exit by default for errors.

If the file has an incorrect name for one of the dimensions or
variables NetCDF by default will call exit.  This has been changed
so that it just gives call vtkErrorMacro and returns 0 for
RequestData().
