from __future__ import unicode_literals breaks fysom

[sjlongland]

The unicode_literals feature is a way to get Python 2.7 code to behave a little more like 3.x code by assuming that string literals are Unicode strings rather than byte strings.

Unfortunately, it breaks fysom:

RC=0 stuartl@rikishi /tmp/fysom $ cat test.py 
from __future__ import unicode_literals
from fysom import Fysom

fysom = Fysom({
            'initial': 'green',
            'events': [
                {'name': 'warn', 'src': 'green', 'dst': 'yellow'},
                {'name': 'panic', 'src': 'yellow', 'dst': 'red'},
                {'name': 'calm', 'src': 'red', 'dst': 'yellow'},
                {'name': 'clear', 'src': 'yellow', 'dst': 'green'},
                {'name': 'warm', 'src': 'green', 'dst': 'blue'}
            ]
        })
RC=0 stuartl@rikishi /tmp/fysom $ python3 test.py 
RC=0 stuartl@rikishi /tmp/fysom $ python2 test.py

Oh shoot, thanks for reporting. In 2.x afaik unicode objects are not strings, but this should be easy enough to fix. Will have a look as soon as I am able, but I reckon a `str()` wrap will do it

I've just quickly thrown together a pull request with a possible fix. I'll see if I can put a quick test case in.

Cool thanks. I'll try to make room for a release tomorrow
