Update public function documentation and address removed spacing

This change inherits the documentation from the parent class definitions
where it can, so our profile proxy can be more in line with others.

It alse seems an auto-formatter removed a lot of the white space in the
class at somepoint. This change puts back spaces between methods and
some of the constants.
