Documentation way out of date

[njovin]

There are several issues with functions requiring callbacks despite the documentation saying they're optional. Most of the samples provided in the documentation simply don't work with the current version. It's very hard for "newbies" such as myself to start using this without googling a bunch of third-party examples.

Hey njovin, sorry you had trouble. Could you specifically point out the problems in a new issue. General comments like this don't help me find the culprits you are speaking of!
