The basics of DiscreteSystem exists now, but the little details around it need to be finished.

The package currently exports these function names:
mm , mmr , hill , hillr , hillar.

To avoid these potentially overwriting other stuff people have decalred, they could be moved to some other sub package. They would then be imported using e.g.

using Catalyst.Functions

Add more design patterns that are currently not present in the repo. Please mention here if you want any pattern to be added. Required language is Kotlin
