Add initial support for writing regulation to a git repo
First draft at getting appendix sections in notices -- doesn't account for parens
Account for parenthetical paragraphs in appendix section, e.g. A-30(d)
Allow appendix citation via a single section (amdpar). Handle 'through' for sections with parens
Consistently assume citation A-33(A)(3) is a reference to header 33(A)(3) of appendix A (rather than header 33, paragraph (A), subparagraph (3))
Header of appendix sections. Allow updates of headers
Better naming + comments
Don't add just one level if a node appears to be missing; add parents recursively
