Application
    createExternalCoupledPatchGeometry.

Description
    Application to generate the patch geometry (points and faces) for use
    with the externalCoupled boundary condition.

    Usage:

        createExternalCoupledPatchGeometry <fieldName>

    On execution, the field <fieldName> is read, and its boundary conditions
    interrogated for the presence of an \c externalCoupled type.  If found,
    the patch geometry (points and faces) for the coupled patches are output
    to the communications directory.

Note:
    The addressing is patch-local, i.e. point indices for each patch point
    used for face addressing starts at index 0.
