I would like to hear your and Ben's views on what the default should
be; it's probably inconvenient for you to keep it switched to unsigned
int if we're still using unsigned char.  But, thanks to structure
padding, an unsigned short or unsigned int is likely to take up 4 more
bytes per element, and Ben sounds quite concerned about memory use
lately.

Also, I need to add some comment up at the definition about what types
are allowed; it looks like PackedElem means that (at least in
parallel) we're still limited to types that can static_cast to and
from int successfully, and the I/O classes probably restrict us to
types that can operator= to and from int successfully.  I guess that's
not a *bad* thing; it'll dissuade people from making subdomain ids
into a bitset or a custom class or something else that'll end up
backfiring on them.
