Ledger Sections

There is a rolonic concept called sections. Each aspect of a rolon has sections and sections can also have sections. Basically I want to make well known into a rolonic ledger section.

Now sections are interesting because their parts can be ordered manually, so sections are lists. but each subsection is named. Now the current implementation of list supports manual ordering, but assigns an ascension number to each part. But it would be easy enough to allow the user to provide a key in place of the ascension number. Then we can change the well known table to be a list and then support a tree of such lists. This then gives us the start of ledger sections.
