Class
    Foam::coordinateSystem

Description
    A cartesian coordinate system and the base class for other coordinate
    system specifications.

    All systems are defined by an origin point and a coordinateRotation.
    For convenience, the dictionary constructor forms allow a few shortcuts:
    - the default origin corresponds to <em>(0 0 0)</em>
    - if the @c type is not otherwise specified, a Cartesian coordinateSystem
      is implicit

    @verbatim
        flipped
        {
            origin  (0 0 0);
            coordinateRotation
            {
                type        STARCDRotation;
                rotation    (0 0 90);
            }
        }
    @endverbatim

    - if an axes specification (eg, e3/e1) is used, the coordinateRotation
      sub-dictionary can be dropped.

    @verbatim
        flipped     // the same, specified as axes
        {
            origin  (0 0 0);
            coordinateRotation
            {
                type    axes;
                e3      (1 0 0);
                e1      (0 0 -1);
            }
        }
        flipped     // the same, using all the shortcuts
        {
            e3      (1 0 0);
            e1      (0 0 -1);
        }
    @endverbatim

    - if a sub-dictionary coordinateSystem is found within the dictionary, it
      will be used. This provides a convenient means of embedding
      coordinateSystem information in another dictionary.
      This is used, for example, in the porousZones:

    @verbatim
        1
        (
        cat1
        {
            coordinateSystem
            {
                origin  (0 0 0);
                coordinateRotation
                {
                    type        STARCDRotation;
                    rotation    (0 0 90);
                }
            }
            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

    - additionally, if the coordinateSystem points to a plain entry,
      it can be used to reference one of the global coordinateSystems

    @verbatim
        1
        (
        cat1
        {
            coordinateSystem  system_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 both a dictionary and an objectRegistry.
