/*
For example, you use Core Data sqlite.
It is necessary, because sqlite database stores data in single file.
Whole database is single file.

Now you have two options.
1. Delete all data from all tables
2. Delete database sqlite file

Second option is clean but complex.

This was nice and fast... but it takes up WAY TOO MUCH space. And it's annoying to write.
(I like the way I can just step into the function that calls the delegate for debugging)

What's a better way to not make me call respondsToSelector in the middle of my code? Some proxy?

    struct {
        unsigned int delegateWillDisplayDocument:1;
        unsigned int delegateDidDisplayDocument:1;
        unsigned int delegateDidShowPageView:1;
        unsigned int delegateDidRenderPageView:1;
