new system for more easily adjusting the constants #1, change unicode
use unicode_literals for better python 2 & 3 support
can now adjust constants like so:

	from nameparser.constants import constants
	constants.titles.add('dean')
	hn = HumanName('dean name')
	hn
        <HumanName : [
            Title: 'dean'
            First: ''
            Middle: ''
            Last: 'name'
            Suffix: ''
            Nickname: ''
        ]>
