Draft Structure

The following is a draft of what a ranking structure could look like. The idea is that this structure would be used as a guideline as to what a kata would be ranked. It would be used in addition to other factors such as average solution length, average time to complete, and possibly other factors.

The emphasis on this structure is to try to create a skills tree that encompases the many aspects of being a complete developer.
