Ah, I misunderstood you! So it is. We hadn't anticipated the need
for applications to access it.
And I'm reluctant to make it public; we've talked about using the
DofConstraints mechanism with a few changes to support strong
Dirichlet conditions, and I'd hate to encourage people to write code
that could be broken by those changes.
Would a couple read-only accessor functions,
DofMap::constraints_begin() and DofMap::constraints_end(), be
sufficient?
