I noticed that DOMWorld was spitting a lot of warnings out when we
generated the docs. It was mostly easy tidy-ups and removing old JSDoc
comments and now the warnings are gone :)
This adds the new docs that are generated by API Extractor via TSDoc.
They are sparse because we do not yet use TSDoc in the codebase. This is
the starting point and from here we can work through all the different
classes and improve the documentation.
