conda package out of date (broken on Python 3.6)

[rishi1999]

The conda package hasn't been updated since 2018-05-04 and is largely non-functional on Python 3.6 due to syntax bugs.

For example, the method tetrad.listScores() causes an error because it attempts to use .sort() on a dictionary. This issue is fixed on this repo, but none of the fixes are in the conda package yet.
