Function of two variables. TODO: 1) Technically, it could have a common parent (e.g. {\tt \hyperlink{classbdm_1_1fnc}{fnc}} ) with other functions. For now, we keep it as it is. 2) It could be generalized into multivariate form, (which was original meaning of {\tt \hyperlink{classbdm_1_1fnc}{fnc}} ). \subsection*{Public Member Functions} \begin{CompactItemize} \item \hypertarget{classbdm_1_1diffbifn_188f31066bd72e1bf0ddacd1eb0e6af3}{ vec \hyperlink{classbdm_1_1diffbifn_188f31066bd72e1bf0ddacd1eb0e6af3}{eval} (const vec \&cond)} \label{classbdm_1_1diffbifn_188f31066bd72e1bf0ddacd1eb0e6af3} \begin{CompactList}\small\item\em Evaluates $f(x0,u0)$ (VS: Do we really need common eval?
