More D3 Pedigree Examples

I couldn't find any good examples of how to use D3 to draw traditional pedigrees (rectangle boxes with straight connecting lines) so made created some. 

There are currently three examples:

* Basic static pedigree

* Expandable and collapsible pedigree

* Expanding and collapsing with transitions (animations)

I anticipate adding an example of how to draw descendants, if I ever figure that out.

Looking great, Justin!  What you've done here already is something that WikiTree members will appreciate.

Looks like you did! What happens when (as is common in real trees) two
ancestors/descendants are actually the same person.

There's a little trick to handling that case. I'll try to show how it's done. Good idea.

Well done! Thanks for sharing!

Ben, I just added a note in the readme about pedigree collapse. D3 doesn't handle it well without significant effort, but it looks like another library designed for display DAGs could help. I haven't had time to investigate though.
