"The package that you are trying to add does not support schematics."

Is your feature request related to a problem? Please describe.
Using ng add @angular-mdc/web give me this error:

The package that you are trying to add does not support schematics. You can try using a different version of the package or contact the package author to add ng-add support.

Describe the solution you'd like
angular-mdc-web to support schematics

Additional context
Obviously this doesn't need to be a high priority feature, but I thought it'd be nice to support schematics.
