- Rename the `near` lambda in Conductor::setPathPoints() to `isNear`:
`near` and `far` are empty macros in the Windows headers (minwindef.h).
- Reword the log when setPathPoints() refuses a route. "does not join the
two terminals" named only one of its reasons; the router always returns
the two terminals and at least one exit point, so a refusal means the
route is not a run of horizontal and vertical segments between them.
- README: running along another wire is penalised, not forbidden, so two
wires can end up drawn on top of each other.
