This patch:
- introduces page.waitForSelector to wait for the selector to appear
- introduces polymorphic page.waitFor method, which accepts
either string (and in this case is a shortcut for page.waitForSelector)
or number (and in this case it's a promisified timeout).
References #91.
This patch:
- adds event linting to the doclint
- improves `api.md` to add events and more information about
classes reported by events.
References #14.
This patch unifies Documentation.Method with Documentation.Property,
making it possible to verify sorting order across methods and
properties.
