Cleaning up RubricCreationRune.java
Preparing to refactor Rubric
Stored structures are working on Rubric from JSON.  We are not currently consuming the rune properly.
Rubric JSON mostly fixed.  Still acting weird about consuming the structure.
Air blocks don't add to the signature.  Added isEmpty() to Signature.
Rubric: Refined named book vs. signature behavior.
