Class
    Foam::coordinateSystems::coordinateSystems

Description
    Provides a centralised coordinateSystem collection.

    For example with the porous region specified in \c constant/fvModels as

    \verbatim
    porosity
    {
        type            porosityForce;

        porosityForce
        {
            cellZone        porousBlockage;

            type            DarcyForchheimer;

            // D 100;  // Very little blockage
            // D 200;  // Some blockage but steady flow
            // D 500;  // Slight waviness in the far wake
            D 1000; // Fully shedding behavior

            d   ($D $D $D);
            f   (0 0 0);

            coordinateSystem porousBlockage;
        }
    }
    \endverbatim

    the corresponding coordinate system \c porousBlockage is looked-up
    automatically from the \c constant/coordinateSystems dictionary:

    \verbatim
    porousBlockage
    {
        type    cartesian;
        origin  (0 0 0);
        coordinateRotation
        {
            type    axesRotation;
            e1  (1 0 0);
            e2  (0 1 0);
        }
    }
    \endverbatim
