-(** The Make module build the main application loop.contents
-
- The function [run] update the state on each event, and return a new state.
- Each event must follow the [event] type, which is composed from the type
- [t], and a module with a fonction [update].
-
- This example create an application with the state containing a simple
- counter. An even which increment this counter is created and can be used to
- update the state.
