Previous to this commit, ontological cross edges were declared
statically. But this doesn't fare well with the decided implementation for
template application.
The documentation details it, but we have Tpl->Ident which could mean "I
define this Ident once expanded", or it could mean "this is a reference to a
template I will be applying". The former is a tree edge, the latter is a
cross edge, and that determination can only be made by inspecting edge data
at runtime.
It could have been resolved by introducing new Object types, but that is a
lot of work for little benefit, especially given that only (right now) the
visitor uses this information.

Now that these are actually intended to be used as part of the build, this
is a more appropriate location. I originally wrote it as a manual tool.

RSG (Ryan Specialty Group) recently announced a rename to Ryan Specialty (no
"Group"), but I'm not sure if the legal name has been changed yet or not, so
I'll wait on that.
This is enabled by default in nightly, and is not available at all in
stable. Considering the PITA that it will be to go back and rewrite docs to
use the new format, and how important of a feature this is, we will just
make use of it now.
