Draft proposed changes to NAME structure

[tychonievich]

A draft of a replacement and extension to personal names based on FamilySearch/GEDCOM#473

I'm submitting this PR just to be hopefully helpful, and because PRs seem to be one of the easier ways for people to comment on and change parts of a document in github. I think this is a reasonable possiblity for moving forward, but am not trying to suggest that it is in any way perfect. Changes or even wholesale replacement with a different proposal are welcome.

I miss the fact you can combine TYPE's. Don't see a description for that.
Further, in Japan it seems titles can go behind a name.
https://en.wikipedia.org/wiki/Japanese_honorifics
https://www.familysearch.org/en/wiki/Japan_Naming_Customs

To denote a sequence TYPE could maybe have PARTFIRST, PARTLAST, PART1, PART2, PART3, PART4 etc.
So textual sequence like first and last, and numberd PART's for numbered sequence,
I used PARTFIRST, because maybe for other TYPE's there could also be a FIRST and LAST.
Because you can combine TYPEvalues, that could work.

CON: The TYPE list would be longer.
