Method	__init__	Create a `Bucket` that may have a parent `Bucket`.
Instance Variable	content	Undocumented
Instance Variable	parentBucket	Undocumented
Instance Variable	lastDrip	Undocumented
Method	add	Adds tokens to the `Bucket` and its `parentBucket`.
Method	drip	Let some of the bucket drain.

def add(self, amount): (source)

Adds tokens to the Bucket and its parentBucket.

This will add as many of the amount tokens as will fit into both this Bucket and its parentBucket.

Parameters	amount	The number of tokens to try to add. (type: `int`)
Returns	The number of tokens that actually fit. (type: `int`)
