Subject: Added Triangular expression to extract upper or lower (strictly or
 not) part of a matrix. Triangular also provide an optimised method for
 forward and backward substitution. Further optimizations regarding
 assignments and products might come later.

Updated determinant() to take into account triangular matrices.

Started the QR module with a QR decompostion algorithm.
Help needed to build a QR algorithm (eigen solver) based on it.
