/*****************************************************************************
  Function name: SizeOfNumberType()

  Purpose      : Determines the size of each number type.  Number type 
                 descriptors are "borrowed" from NetCDF.

  Required     :
    NumberType - descriptor of number type (for more info see comments in 
                 InitFileIO.c)

  Returns      : size of number type

  Modifies     : NA

  Comments     :
   Information about the number type has to be passed to the functions that
   deal with 2DMatrix.  The number types are adopted from the NetCDF standard.
