Write more examples

[CoffeeStraw]

Examples are never enough. Any contributions showing particular usage of implemented functions would be appreciated.

After some refactoring of available kfx scripts with more comments and cleaner code they could serve as good examples. Reviewing them and collecting different levels of difficulty would result in a helpful set.

The only (old) problem would be copyright - many people just copy effects and publish as their own work so contibutors should be wary of that!

Good point, probably I need to update contribution guidelines and add a readme in the examples directory.
