feature request:

Support querying of tiles directly.

What is the expected behavior?

@ViewChildren(MdGridTile) tiles: QueryList<MdGridTile>;
myMethod() {
    this.tiles.changes.subscribe(changes => { ... })
}

What is the current behavior?

@ViewChild(MdGridList) list: QueryList<MdGridList>;
myMethod() {
    this.list._tiles.changes.subscribe(changes => { ... })
}

What is the use-case or motivation for changing an existing behavior?

I want to have a count of the *ngFor piped tiles

Which versions of Angular, Material, OS, browsers are affected?

Is there anything else we should know?

Using JSPM and SystemJS to import default JS files.
