this is similar to the constants defined in "ublas::bounded_vector" and
"ublas::bounded_matrix". I think they are named "max_size", "max_size1" and
"max_size2". But the solution in MTL looks nicer indicating as well if the
array has a static size or not.
Shouldn't there be a N and a max_N?
if (N == 0) the size is flexible
if (max_N == 0) the maximum size is flexible
But, must it be guranteed that a vector can be resized to max_N or
max_size() without errors?
