Clean up module vs class descriptions, +@since 3.5.0 Moved the lengthy text from the module description to the class description so the module page would look cleaner. Added note for each class extension to point readers to the DataTable class for docs on the APIs contributed by this class, since they all have @for DataTable.

Fix API docs so DataTable class shows up

Add (probably too exhaustive) API docs

Initial drop of DataTable rearchitecture Renders a table from supplied columns and data as a ModelList with Model instances. A lot more plumbing in place, but not yet exercised. Progressive enhancement extension in src/pe.js, but doesn't have build files yet.
