import errors due to dash

[reddishtg]

Line 7 of setup.py shows the name as follows: name="tkinterdnd2-pmgagne", #Replace with your own username

The hyphen here creates issues when importing unless we want to edit the setup.py to remove it before using. Can this be adjusted to an underscore or simply removed? It does not seem to be consistent with the demos this way unless I'm missing something.
