There are a few things I ended up deciding not to document for this 
release, but they're mostly things that might end up changing, and 
are semi-internal or "experts only" stuff, like poll(), repeat(), and 
ensure_recalculation().

Next up after this is work on the TrellisDB package and its 
dependencies (i.e., Contextual and PEAK-Rules).  As part of that 
work, the main Trellis code is likely to also get some support for 
integrating with Contextual, and I'll be implementing more formal 
"hub" and "spoke" features (and the priority-heap recalculation 
algorithm that's needed for them).

This stuff will probably surface in 0.5b2, unless it ends up shaking 
things up enough to call it 0.6b1 instead.  :)
