ublas containers are designed to have a static size. Inserting a new row can
only be implemented as creating a new larger matrix an copying the data. If
you frequently need to insert/remove whole columns the std::list type may fit
much better.
It is possible to resize all ublas data types, but usually you either lose all
data or the old data is copied once.
