Detailed Description
       This depends on Metal.framework.

       A kernel for computing the solution of a linear system of equations using the Cholesky factorization resulting from a
       MPSMatrixDecompositionCholesky kernel.

       A MPSMatrixSolveCholesky finds the solution matrix to the system:

		   A * X = B

	       Where A is symmetric positive definite.	B is the array of
	       right hand sides for which the equations are to be solved.
	       X is the resulting matrix of solutions.

Method Documentation
   - (void) encodeToCommandBuffer: (nonnull id< MTLCommandBuffer >) commandBuffer(MPSMatrix *__nonnull) sourceMatrix(MPSMatrix *__nonnull)
       rightHandSideMatrix(MPSMatrix *__nonnull) solutionMatrix
       Encode a MPSMatrixSolveCholesky kernel into a command Buffer.

       Parameters:
	   commandBuffer A valid MTLCommandBuffer to receive the encoded filter
	   sourceMatrix A valid MPSMatrix containing the source matrix in factored form as returned by a previous successful execution of a
	   MPSMatrixDecompositionCholesky kernel.
	   rightHandSideMatrix A valid MPSMatrix containing the right hand side values.
	   solutionMatrix A valid MPSMatrix to contain the result.

       This function encodes the MPSMatrixSolveCholesky object to a valid command buffer. sourceMatrix should contain either the lower or upper
       triangular factors corresponding to the factorization returned by a previous execution of MPSMatrixDecompositionCholesky.

       rightHandSideMatrix and solutionMatrix must be large enough to hold a matrix of size order x numberOfRightHandSides starting at
       secondarySourceMatrixOrigin and resultMatrixOrigin respectively.

       sourceMatrix must be at least size order x order starting at primarySourceMatrixOrigin.

   - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(BOOL) upper(NSUInteger) order(NSUInteger) numberOfRightHandSides
       Initialize an MPSMatrixSolveCholesky object on a device

       Parameters:
	   device The device on which the kernel will execute.
	   upper A boolean value which indicates if the source matrix stores the lower or upper triangular factors.
	   order The order of the source matrix and the number of rows in the solution and right hand side matrices.
	   numberOfRightHandSides The number of columns in the solution and right hand side matrices.

       Returns:
	   A valid MPSMatrixSolveCholesky object or nil, if failure.
