Test for sparse matrix range check

There is no range check for sparse matrices:

For a standard SparseMatrix<double, Dynamic> (row major format?), elements above the upper column limit can be inserted, e.g. an element in column 11 in a 10 x 10 sparse matrix. There is no error or exception thrown.

Inserting an entry above the row limit usually leads to a segmentation fault.

Both behaviors are demonstrated in the example code attached.
