Implement `generate.py` script to build topologies from `config.yml` files

[aridyckovsky]

Summary

A script that opens YAML config files within studies, builds the networks, and writes them to file.

Motivation

Using the generate.yml workflow for GitHub Actions, this will enable version controlled topological structures that we use in Empirica experiments with interactive networks.

Implementation

• Uses glob to find all studies with a config.yml file
• Validate config.yml for expected data #3
• Loads valid configs using yaml package, e.g., config = yaml.safe_load(file)
• Generates topologies
• Writes topologies to file
• Implement sequence.py to find dyadic conversation sequence #4
• Test that this works with the small_world generator from Implement small_world function #1

Additional context

Any other context or screenshots.

[aridyckovsky]

Currently generate.py script can be run with GitHub Actions, successfully printing a config's data as a dict of dicts.

With the generate.yml workflow for GitHub Actions, the generate method now writes 'official' generated topologies to id-sequenced directories. For instance: studies/moralnet/topology_001 has both diagram.png and metadata.json files, which describe the generated topology from NetworkX using the config.yml inputs.
