Kit API docs return a 404

[divisuals]

Seems the API docs are broken in the new site.

By default, the <sedona_home>/adm/makedoc.py generates api docs in build/doc/api folder. If the <sedona_home>/doc folder is setup as mkdocs home directory, api docs would not be available at that location.

Should be a fairly quick fix.

I had fixed the kit broken api documents and deployed on document site.

I will create a pull request later, there are some broken tests need to be fixed first.
