/*******************************************************************************
  Function name: Read2DMatrixNetCDF()

  Purpose      : Function to read a 2D array from a file.

  Required     :
    FileName   - name of input file
    Matrix     - address of array data into
    NumberType - code for number type (taken from HDF, see comments at the
                 beginning of InitFileIO.c for more detail)
    NY         - Number of rows
    NX         - Number of columns
    NDataSet   - number of the dataset to read, i.e. the first matrix in a 
                 file is number 0, etc. (this is not used for the NetCDF file,
		 since we can retrieve the variable by name).
    VarName    - Name of variable to retrieve

  Returns      : Number of elements read

  Modifies     : Matrix

  Comments     : NOTE that we cannot modify anything other than the returned
                 Matrix, because we have to stay compatible with Read2DMatrixBin
