[seldom_state] is a Bevy plugin that adds a `StateMachine` component that you

can add to your entities. The state machine will change the entity's components

based on states, triggers, and transitions that you define. It's useful

for player controllers, animations, simple AI, etc.

This month [seldom_state] 0.4 has been released:

- Transition builders (`StateMachine::trans_builder`) which let you pass data

from triggers to states.

- The `AnyState` state, which you can use wherever `StateMachine` accepts state

type parameters, which lets you create transitions from any state, etc

- A `leafwing_input` feature for `leafwing-input-manager` integration,

which enables 9 built-in triggers related to input. `JustPressedTrigger`,

for example.

- `OptionTrigger` and `BoolTrigger` traits, which are simpler to implement

than `Trigger`.
