LED "Enumeration"

[Brandyn]

I was interested in programming in WorldViz to "enumerate" available LED markers upon the script being ran. Enumeration, in this case, just means to find the maximum number of markers and to have filled a list with all the markers it added.

The only roadblock I see to this is that I'm wondering if there is a null check I can use to tell if the last marker added was "real" or not. It seems to add markers whether or not it has found additional ones-- Should a basic Null check work for this, or would I have to check the data object in each for a marker that had co-ordinates of (0,0,0)?
