Proposed Stripe Python syntax for multiple subscriptions

multisub.py

# create a new subscription
customer.subscriptions.create(plan='basic')

# delete a subscription
customer.subscriptions.retrieve(subscription_id).delete()

# update a subscription
subscription = customer.subscriptions.retrieve(subscription_id)
subscription.trial_end = modified_trial_end
subscription.plan = subscription.plan.id  # if possible, change API to make this superfluous.
subscription.save()
