Class
    Foam::coordinateSystems

Description
    A centralized collection of named coordinate systems.

Note
    Mixing normal constructors and the coordinateSystems::New constructor
    may yield unexpected results.

    \verbatim
    cat1
    {
        coordinateSystem
        {
            type   indirect;
            name   _10;
        }
        porosity    0.781;
        Darcy
        {
            d   d [0 -2 0 0 0]  (-1000 -1000 0.50753e+08);
            f   f [0 -1 0 0 0]  (-1000 -1000 12.83);
        }
    }
    \endverbatim

    For this to work correctly, the coordinateSystem constructor must be
    supplied with an objectRegistry as well as the dictionary.
