Update paypal-subscription.class.php
Update README.md

It seems paypal now requires the notify url to be set or an error will be returned. Added this line so the example configuration will work without issue.
Update README.md

Paypal now requires 'tax_amount' to be set. Also the totals were wrong and were throwing an error. The way they are added up is counter-intuitive so I added comments to clarify.
Edited intro text so it reads easier

It was already fine but just added a missing word and made a couple edits so the summary text reads easier. Slight improvement for the troubled mind of any programmer who came here after mucking through paypal's docs for the past 2 hours.
