mention need for driver.close() in README

[ballPointPenguin]

Although the README is far from exhaustive and people should be directed to https://neo4j.com/developer/javascript/, a mention of the need to call driver.close() would be very helpful.
I could not figure out why my scripts were not cleanly exiting and spent a lot of time debugging session.close() looking for answers.

Thanks very much for this feedback. We will improve our readme. And you could find more good examples in http://neo4j.com/docs/developer-manual/3.0/drivers/

@ballPointPenguin @zhenlineo Would this have to do with #148 at all? I don't have driver.close() anywhere...

@booboothefool I guess it could. In node environment absence of driver.close() results in the program not being able to exit.
