The check finds usages of ``sizeof`` on expressions of STL container types.

likely the user wanted to use ``.size()`` instead.
-Currently only ``std::string`` and ``std::vector<T>`` are supported.
+All class/struct types declared in namespace ``std::`` having a const
``size()``
+method are considered containers, with the exception of ``std::bitset`` and
