This class defines a simple data structure for a flat 2-dim square matrix whose entries are stored in a single array.
Additional classes for a row and a constant row are defined within this class which allow to use the usual double indexing to get to the entries of the matrix, both for reading only and for modifying the entries, e.g., M[0][1].
