Class
    Foam::Function1s::crankConnectingRodMotion

Description
    Crank and connecting-rod motion function for piston engines etc.

    \c value returns the current piston position as a function of
    the crank-angle in degrees.

    Usage:
    \verbatim
        <name>
        {
            type            crankConnectingRodMotion;

            conRodLength    0.2;
            stroke          0.12;
        }
    \endverbatim
