0088 - Vertex Barrel Modules.
0089 - For RSU (1 module = 1 upper/lower section of three tiles):
0090 --Use [mod_name]_upper and [mod_name]_lower here, and [mod_name] in corresponding layer
0091 to allow the geo plugin find both modules.
0092 -- also need to specify type="upper" or "lower" in components.
0093 - for other modules and components:
0094 no need to specify upper and lower anywhere.
0095 - one RSU ("|" = backbone. Length alone z.):
