Create createSelectors for similar functionality to createFeature for deeper properties of state

[david-shortman]

The new createFeature functionality handily provides selectors which can be exported by destructuring the feature object.

But, this only provides selectors for top-level fields.

It would add convenience and cut boilerplate if there was a way to generate basic selectors from other selectors.

Suppose createSelectors existed like so:

export const selectSomething = () => ({ one: 1, two: 2, three: 3 });

export const { selectOne, selectTwo, selectThree } = createSelectors(selectSomething);

You can use createChildSelectors from ngrx-child-selectors package: https://github.com/markostanimirovic/ngrx-child-selectors#createchildselectors

I think that’s pretty cool. Have you considered it being a strong inclusion in core ngrx? It seems more natural now that createFeature is included out of the box.
