Problems installing Cytoolz

[scottkleinman]

Installing Cytoolz can lead to permission errors on Windows if VS 2019 Desktop development for C++ is not installed. There should be a fallback to plain Python Toolz if Cytoolz is not available, but there needs to be a way to make the installation of Cytoolz optional.

It might require tutorial instructions to install Cytoolz separately.

Apparently, Cytoolz 0.12.0 will install even if you have not downloaded VS 2019 Desktop development for C++, but you do need to run pip install cytoolz before installing Lexos. If using Anaconda, it may be preferable to run conda install -c anaconda cytoolz.

I won't close this issue until the documentation is updated at the least.

This issue has apparently been resolved. See:
