fix(docs): order class members in order of declaration

Previously, class members were ordered alphabetically.
This change leaves it up to the class author to
determine the order in which they would like
properties and methods to appear in class
documentation, without having to create methods like
`zUnimportantMethod`.

Fixes #2569
