Aggregate

=========

`Aggregate` is an object which can compose protocol implementations from various objects

This can be useful for dividing large protocol implementations into separate objects,

and then combining them here to pass to a client as a single delegate, data source, or object.

```swift

import Aggregate

@objc protocol Foo {

    func doThis()

}

@objc protocol Bar {

    func doThat()

}

@objc EagerBeaver: NSObject, Foo {

    func doThis() {

        print("I did this!")

    }

}

@objc Underachiever: NSObject, Foo, Bar {

    func doThis() {

        print("Do I have to do this?")

    }

    func doThat() {

        print("Do I have to do that?")

    }

}

let averageJoe = Aggregate(of: [EagerBeaver(), Underachiever()]) as! Foo & Bar

averageJoe.doThis() // prints "I did this!"

averageJoe.doThat() // prints "Do I have to do that?"

```

It is important to note that the order of objects in the `targets` array denotes the calling 

order for composed objects with duplicate method implementations, where the first target

has the highest prioritization. This is why `Underachiever`'s `doThis` implementation wasn't

called in the previous example.
