Navcord stands for "navigation cord". I try to prefix anything that is
specific to the navmesh with the "nav-" prefix. I chose the word "cord"
as analogy to the terms "umbilical cord" (and by extension, umbilical
cable), and "power cord".
Calling this "trace" was misleading, as this term has other meanings
that are relevant to Topola: "trace" may refer to a debugging trace, and
more importantly, to a PCB track.
I've also shortened two comments that I found to mention the navcord as
"traces" during substitution.
