Hi, thanks for putting together a pull-request. I had planned to do one when I had some free time, but this is all I would do. Looks good

No problem., this was a fairly simple one :-). Please do feel free to contribute if you see anything else amiss. This has now been merged in DigiMesh should now work with Python 3.
