0.0.10 Documentation checkpoint.
The vast majority of the Maple-specific values have been pulled out of
the higher-level overview pages and replaced with refs into documents
under /docs/source/hardware/.
Much of the work that's left to be done in this regard is labeled with
versioned TODO and FIXME comments.
Suggestions from StephenFromNYC and gbulmer were incorporated from
this forum thread:
