functionObjects::cylindrical: Added packaged configuration

This function can now be run interactively using the following command:

    foamPostProcess -func "cylindrical(origin=(0 0 0), axis=(0 0 1), U)"

Or it can be executed at run time by adding the following entry in the
system/functions file:

    #includeFunc cylindrical(origin=(0 0 0), axis=(0 0 1), U)
