Calling functions of other classes

There isn't much involvement as far as CI is concerned, that is why it's easy to make libraries you can find on the web to work with CI.

The only thing you have to be aware of is that if you want to use CI methods you have to use the get_instance function. If you are using CI methods in several of your methods it's best you assign the get_instance function to a variable.

With extending CI libraries you have to see how the CI methods are connected to the loaded libraries. For instance the language library uses in all the methods an own get_instance object.
