Hello all,

 I've been used the matrix row/column range successfully. Also, I've
modified the code of Oswin and I've generalized a little:

- Added reverse iterators.
- Resize of matrix
  * From matrix_row facade the number of rows of the matrix could be
changed but not the number of columns.
  * From matrix_column facade the number of columns of the matrix could be
changed but not the number of rows.

I would like to update the source code to ticked 7411 if there is no
inconvenient for your part. I've followed the style of Oswin. Also, I've
provided an executable but not tests cases, as Oswin did,
