MatConcatDiag

create a simple block matrix
Syntax 

MatConcatDiag(A:LIST, MAT, B:LIST, MAT):MAT

Description
This function creates a simple block matrix. The two entries are matrices (or lists cast-able to a matrix). MatrixConcatDiag(A, B) will return a matrix of the form 
                | A 0 |
                | 0 B |


Example 
  A := [[1,2,3],   [4,5,6]];
  B := [[101,102], [103,104]];
  MatConcatDiag(A, B);
Mat([
  [1, 2, 3, 0, 0],
  [4, 5, 6, 0, 0],
  [0, 0, 0, 101, 102],
  [0, 0, 0, 103, 104]
])
