Problem/Feature

This is just the foundation to add more advanced features referenced in this issue. I wanted to get this in to make sure I was on the right track with where we want this to go.

Description of Changes:

• Adds an optional --advanced or -a flag to the create command.
• I didn't add anything to the README yet, pending approval on the direction.

I was thinking we might want to wait to merge this until we get one advanced feature added. Maybe we make an 'advanced' branch that we can merge into?
