Full Spectrum Bioinformatics Development Release 2020.12.1

This is an initial development release of the Full Spectrum Bioinformatics online textbook. This is not a full release of the entire planned textbook, but rather an incremental development release of some content that is sufficiently developed that it has been used in classes.

Some current features include:
-- A series of open-access Jupyter Notebooks discussing topics in Bioinformatics.
-- Links to Google Colab to allow students to run notebooks in a browser without installing software
-- An outline table of contents shows planned sections, with sections that are in beta status available as live links.
-- This release includes 21 new sections, covering topics ranging from sequence analysis to how to revise one's writing about statistical results:

NOTE: this is very similar to release-2020.12.0, other than minor edits to the readme but I need to re-release to trigger Zenodo to generate a DOI.
