/*******************************************************************************
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
