## Rat-Event
This crate defines a general event-handling trait,
that can be used to create ratatui widgets.
The main idea here is _not_ to try to unify the different event sources.
Instead, provide a trait that can be implemented once per event-type.
And as there seem to be widely diverging opinions on what the right
key-bindings should be, we add a marker type to allow for more than
one key-binding.
If the widget is designed in a way, that each key binding only needs to call
a function or two, the code duplication is negligible.
This accomplishes:
* Widget author can support different event types.
* Widget author can supply several key bindings.
* Application author can define ves own key bindings, and as the
widget is designed this way it's possible to do this.
* As there is a trait for this, widgets can be composed generically.
