Delete Empty Elevation Marker Tags

It is pretty common for a model to end up with a bunch of abandoned elevation marker tags. There are a bunch of ways that this can happen and depending on how you have your elevation tag symbols defined can be difficult to find visually for removal.

One of the supreme beings that I used to work with at CASE built a means of doing this in Dynamo.

This is a simple routine that finds these and eradicates them from your model...
