Tutorial or other complete examples

[c-prather]

Now that pyharm is (relatively) stable and has its core functionality worked out, it should have a better tutorial than an outdated Jupyter notebook or help text on scripts. Ideally this should involve:

• Sample data from of some kind from e.g. KHARMA, preferably of an actual accretion disk in 2D or similar
• Command-line usage of scripts
• Numerical investigation with a Jupyter notebook, including plotting and calculation of basic diagnostics
• Illustration of adding/standardizing elements of analysis as plugins to pyharm-movie or pyharm-analysis
