documentation for quick running for mac should be better

[tcab]

On the mac, the instructions in the readme

PYTHONPATH=/path/to/kivy_statecharts python main.py

did not work. Instead I had to

export PYTHONPATH=/Users/andy/Desktop/kivy-examples/kivy-statecharts-master
kivy main.py

Note that it should be made clear that the path is the kivy-statecharts-master directory (or whatever its names) and not the package directory kivy_statecharts within. This might trip up people too.

Users need to of course generate the kivy script during the install process.

Thanks for this note. The approach may indeed take a script to prepare the environment.
