- `Pattern` objects also contain `Port` information, which can be used to "snap" together
multiple sub-components by matching up the requested port offsets and rotations.
* Port rotations are defined as counter-clockwise angles from the +x axis.
* Ports point into the interior of their associated device.
* Port rotations may be `None` in the case of non-oriented ports.
* Ports have a `ptype` string which is compared in order to catch mismatched connections at build time.
* Ports can be exported into/imported from `Label`s stored directly in the layout,
editable from standard tools (e.g. KLayout). A default format is provided.
