utility::matrix has internal support for const matrix views but there is no interface to create a const matrix view

[Jari Häkkinen]

There is a test in matrix_test.cc that must be fixed when resolving this ticket. Look for a comment with ticket:202 in the code, this will point you to the code that needs to be changed.

Related to this is that the following constructor should be removed from interface. It is a flaw to allow thos constructor because it creates a huge hole against const correctness.

vector(const vector& v, size_t offset, size_t n, size_t stride=1);
