Source code for optixstuff._repr

"""Shared formatting helper for hierarchical ``__repr__`` methods.

Each leaf class in optixstuff (primary, detector, throughput elements,
coronagraphs) defines its own one-line ``__repr__``; the
:class:`OpticalPath` aggregator uses :func:`indent` to nest the
children one level deeper. Same pattern as ``skyscapes._repr``.
