 * First Code Sample.
 *
 * Make a class which you would pass the components of someone's name
 * (first name, last name) to the constructor, and have two functions
 * callable off of the object:
 *
 * 1. Simply print out the whole name, i.e. "John Smith"
 * 2. Print out the name in phone book fashion, i.e. "Smith, John"
 *
 * (Don't worry about validating empty strings.)

Initial commit with class specification.

Flesh out PersonName class.

Add PHPUnit tests. Though, current PersonName class methods print strings rather than return strings.
