; Detailed Descendant Report -- option for reporting by-branch

This patch implements an EnumeratedListOption called Report structuring system ('structure') with two possible values, "by generation" and "by branch". Cf. Paes Leme, Pedro Taques de Almeida, Nobiliarchia Paulistana, Genealogia das Principaes Familias de S. Paulo, and Felgueiras Gayo, Manoel Joze da Costa, Nobiliario de Familias de Portugal, etc. I plan an implementation of the numbering systems used by Pedro Taques de Almeida Paes Leme and Manoel Joze da Costa Felgueiras Gayo.
