                                                  DivisiveNormalizeL1

OutputFn that divides an array by its L1 norm.

This operation ensures that the sum of the absolute values of the array is equal to the specified norm_value, rescaling each value to make this true. The array is unchanged if the sum of absolute values is zero. For arrays of non-negative values where at least one is non-zero, this operation is equivalent to a divisive sum normalization.
