Detailed Description
       This depends on Metal.framework.

       A logarithmic softmax kernel that operates on matrices.

       A MPSMatrixLogSoftMax object computes:

		   B_ij = ln { Exp { A_ij } / ( Sum_k Exp { A_ik } ) } = A_ij - ln { Sum_k Exp { A_ik } }

	       A and B are matrices which are represented by MPSMatrix
	       objects. This filter computes the same result for MPSMatrices as
	       MPSCNNLogSoftMax filter does for MPSImages by interpreting the columns
	       of the matrix as feature channels, that is the sum runs over column indices.
