Update methods section with current available methods

Updated methods section of docs, with currently available methods. 
Added brief explanations to those that I have added.
Removed configuration section of docs as it appeared out of data and/or misleading.
Broke up larger paragraphs to make a little more readable.
You can also pass them in using `setIdentifiers()` and/or `addIdentifiers()` on the `EventManager` instance. Not sure if we should mention that here or not, though. Maybe in a note?
