Concurrencies starting/ending at a hidden waypoint

Jim:
Another issue has arisen while I'm working on my graphs of our highway data where something I assumed was impossible happens quite a bit.

The assumption: a concurrency cannot start/end at a location occupied only by one or more hidden waypoints. It is possible to have an endpoint of a concurrency at a location where at least one waypoint is visible - see Si's example of I-22/US 78 at what will some day be I-269. That I don't have a problem with.

My intended use of the assumption: there must be exactly two unique places you can go from a location that is occupied by only hidden waypoints.

What I found: when this assumption is broken, it can be a symptom of a broken concurrency. For example see the US20/MA8 example below. They use different coordinates for the eastern/southern end of their concurrency.

Not urgent, but if you see things that appear to be in your regions, could you have a look through for possible broken concurrencies indicated by the list of error messages I'm generating, shown below?

Could the list mention the regions that the errors are in? Would make it a lot easier to ID any problems in my areas.

Ok, I've figured out both of these errors. It seems that when @mapmikey was creating the SC files for that state, he didn't (at least here) copy the coordinates out of the US-321 file for the start/end intersections along this multiplex with SC-34. Same type of error with the US-221 one. I'm working on fixing both at least right now. (Pull Request #644)

However, I would recommend to @mapmikey to double check all of the other start/end locations for multiplexes of State Highways w/ US Highways to make sure everything is synced so that the concurrencies are properly triggered.

This might make a good datacheck.
