Heterogenous container implementations

\begin{enumerate}

\item Use polymophism-all objects derive from common base. use \(<\)dynamic\_cast\(>\).
Recompile everything for each new element.

\item Create base class for container. Anything that goes in container derives
from it. Make pure virtual functions to match access to objects. Not
as flexible.

\end{enumerate}
