Import issues, cannot import name 'append_configs' from 'cadCAD.configuration'

[le-dawg]

I have run into this for a few weeks now and prevents me from running this in the default configuration.

Environment is Windows 10, Anaconda recent with venv activated.

In some cases, this becomes a problem right at the beginning from cadCAD.configuration import *.

**Manual import works - until: **
name 'append_configs' is not defined when attempting to execute the simulation.

Instantiating Experiment() with

testex = Experiment()
testex.append_configs(...)

uncovers a deeper issue with networkx (see other issue)

Is this a potential root cause?

`import sys
sys.path.append("../../venv/lib/python3.7/site-packages")`
