CCT combines a number of commonly requested covid related tasks into an easy(ish) to use package.
- Create a node network hierarchy from the pangolin lineages and aliases
 - Cache that data locally in case of remote data or access problems
 - Query that network for ancestors and descendants of a lineage
 - Parse constellations into a easily used table
 - Parse the covariants.org variant table
 - Expand all the variants in that table into their children
 - Sort lineages by ancestry instead of alnum
