Usage notes
Example
The following example shows how to extend an existing list of factories,
which will only be applied to the injector for this component and its children.
This step is all that's required to make a new IterableDiffer available.
@Component({ viewProviders: [ IterableDiffers.extend([new ImmutableListDiffer()]) ]})
