Description
    Initialises fields with default and zone values
 
    The default and zone values are read from a dictionary which defaults to
    system/setFieldsDict, cellZones are used to specify the internal field
    values and faceZone patch field values.
 
Usage
    Any number of fields can be initialised on any number of zones, for
    example the 1D shock tube is initialised by
    \verbatim
        defaultValues
        {
            U       (0 0 0);
            T       348.432;
            p       100000;
        }
 
        zones
        {
            lowPressure
            {
                type        box;
                zoneType    cell;
 
                box         (0 -1 -1) (5 1 1);
 
                values
                {
                    T       278.746;
                    p       10000;
                }
            }
        }
    \endverbatim
    and the water in the tank of the rotatingCube VoF case is initialised by
    \verbatim
        defaultValues
        {
            alpha.water 0;
        }
 
        zones
        {
            cells
            {
                type        box;
                zoneType    cell;
 
                box (-1e300 -1e300 -1e300) (1e300 0 1e300);
 
                values
                {
                    alpha.water 1;
                }
            }
 
            patchFaces
            {
                type        box;
                zoneType    face;
 
                box (-1e300 -1e300 -1e300) (1e300 0 1e300);
 
                values
                {
                    alpha.water 1;
                }
            }
        }
    \endverbatim
    which sets both the internal and inlet values of the patch phase-fraction
    field.
