Common hooks for Dioxus

This crate includes some basic useful hooks for dioxus:

• use_state
• use_ref
• use_future
• use_coroutine

use_state

The primary mechanism of stored state.

You can always use it "normally" with the split method:

```rust // Rusty-smart-pointer usage: let value = use_state(&cx, || 10);

// "Classic" usage: let (value, setvalue) = usestate(&cx, || 0).split(); ```
