Function createDelegateContext

createDelegateContext<P, E>(): DelegateContext<P, E>
Creates a context that merges delegated props and refs.

Context children are re-rendered if props or ref is changed.

If a provider is nested in a provider of the same delegate context, then it merges its props and ref with props and ref received from the enclosing provider.
Type Parameters
- P = {}
  Delegated props.
- E = any
  An element to which props are delegated.
Returns DelegateContext<P, E>
A context that carries delegated props and a ref.
Example
```
// 1. Create a context
const MyContext = createDelegateContext<{ foo: string }>();

// 2. Use context in a component
function Bar() {
  const { props, ref } = useContext(MyContext);

  // Use props and ref here
  return props.foo;
}

// 3. Render a provider and delegate props and ref to a child component,
<MyContext.Provider props={{ foo: 'hello' }}>
  <Bar/>
</MyContext>
```
