Camilla Berglund 3e78570a31 Removed duplicate documentation.
The public, platform, native, event and utility functions are already
documented in-source.  Having duplicate documentation inevitably means
having them contradict one another.  Furthermore, most of the function
descriptions simply repeated the name of the function.
