returns the tensor product of two matrices
Syntax 

TensorMat(M:Mat, N:Mat):MAT

Description
This function returns the tensor product of two matrices.

Example 
  Use R ::= QQ[x,y,z,w];
  TensorMat(Mat([[1,-1],[2,-2],[3,-3]]), Mat([[x,y],[z,w]]));
Mat([
  [x, y, -x, -y],
  [z, w, -z, -w],
  [2x, 2y, -2x, -2y],
  [2z, 2w, -2z, -2w],
  [3x, 3y, -3x, -3y],
  [3z, 3w, -3z, -3w]
])
