Books should have a tree structure #14

Remove the code that flattens Book structure to a single level, allowing the user to build trees. Calling a fill from the top level should still propagate all the way down.

This is a prerequisite for making special Books representing semantic relationships among histograms. You lose meaning if the structure gets flattened.

Books are nestable in a tree structure.
