DOC: use custom module reset function to fix unit registration

tacaswell · tacaswell · commit cfdebd9f5131 · 2022-07-29T15:29:27.000-04:00
As of sg 0.11 the unit registry is reset for each example.  This also forces
the basic_unit module to be fully re-imported to re-register in any example
that use it.
