gramps/gramps2/src/RelLib/_Person.py
Alex Roitman fb1b7b3744 * src/GrampsDb/_GrampsBSDDB.py (gramps_upgrade_9): Convert upgrade 
to using new birth/death reference approach.
	* src/GrampsDb/_GrampsDbBase.py (commit_person): Simplify updating
	of the custom event roles.
	* src/GrampsDb/_WriteXML.py (write_person): Use methods to get
	birth/death ref, not raw attributes.
	* src/RelLib/_Person.py: Convert to using birth and death ref
	indices.
	birth/deat reference; use methods to get birth/death ref, not raw
	attributes.

Introduction
============
The Person record is the GRAMPS in-memory representation of an
individual person. It contains all the information related to
an individual.
Usage
=====
Person objects are usually created in one of two ways.
1. Creating a new person object, which is then initialized and
added to the database.
2. Retrieving an object from the database using the records
handle.
Once a Person object has been modified, it must be committed
to the database using the database object's commit_person function,
or the changes will be lost.
@sort: serialize, unserialize, get_*, set_*, add_*, remove_*

Converts the data held in the Person to a Python tuple that
represents all the data elements. This method is used to convert
the object into a form that can easily be saved to a database.
These elements may be primative Python types (string, integers),
complex Python types (lists or tuples, or Python objects. If the
target database cannot handle complex types (such as objectes or
lists), the database is responsible for converting the data into
a form that it can use.
