Bugs with get_name and get_marriages

[damonbrodie]

I've created a PR (#8) that addresses the following bugs:

1. get_marriages. This method returns a Tuple that has the date and location. It was being assembled incorrectly. If there was a single marriage on Oct 5, 2000 in location Canada, then it was returning two marriages one with date="Oct 5, 2000", location="" and a second marriage with date="", location="Canada".

2. get_name was iterating through all the NAME records and returning the last one found. Typically the first NAME record is the "preferred" record, and it should be what is returned with get_name
