## Feature Implementation

I'm guessing this is meant to be a convenience method to set both the first and last name from a full name. If so, my first question would be does this actually save to the database? `first_name=` only sets the in memory attribute. Also, I think it's unnecessary to call split on name twice. would prefer storing it in a local variable first.
