Is this copyright declaration intentional?

[brandonroberts]

Some of the schematics were created from examples in the Angular schematics so I wasn't sure whether to remove them all or leave them.

@peterbsmith2 I'm glad you're excited about schematics! The initial work in this PR is pretty much done pending review. What I'd like to do is get this reviewed and merged in so we can generate some nightly builds and get some people from the community to use it and provide feedback before it's published as official.

If you have anything you'd specifically like to see besides what's listed in the PR, add it to #53.

[MikeRyanDev]

This is looking good to me so far. Are we waiting for the tests to turn green before removing the WIP?

[brandonroberts]

I'll go ahead and remove the WIP and get the build green so we can merge it.

@brandonroberts I will want to tinker with this on nightly-builds. You can let me know the best way to get that start. I can be available for any cooperation you need.
