In my code, I'm currently just generating my mesh using

In this routine, I see it setting boundary ids for the sides, but I don't see
anywhere it sets them (or would set them)
for the nodes. Where would be the appropriate place to set this? I'm just
wanting the entire boundary to be Dirichlet.
I seem to recall that, when adding a boundary id for a side, the nodes
for that side are given the same id, possibly overwriting any existing
id of their own.
Searching through the library, I can find absolutely no hint that any
such behavior exists. I'd say that it might be a useful idea to at
least add a method like "BoundaryInfo::sync_sides_to_nodes()" to
loop over all elements and set node ids after the fact, but at the
moment I'm more concerned about how I hallucinated a memory of code
that never existed...
