Hierarchical Token Bucket traffic shaping.

�Bucketa�
    Implementation of a Token bucket.

    A bucket can hold a certain number of tokens and it drains over time.

    @cvar maxburst: The maximum number of tokens that the bucket can
        hold at any given time. If this is L{None}, the bucket has
        an infinite size.
    @type maxburst: C{int}
    @cvar rate: The rate at which the bucket drains, in number
        of tokens per second. If the rate is L{None}, the bucket
        drains instantaneously.
    @type rate: C{int}
    N�maxburst�ratercCsd|_||_t�|_dS)a(
        Create a L{Bucket} that may have a parent L{Bucket}.

        @param parentBucket: If a parent Bucket is specified,
            all L{add} and L{drip} operations on this L{Bucket}
            will be applied on the parent L{Bucket} as well.

        Adds tokens to the L{Bucket} and its C{parentBucket}.

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

        @param amount: The number of tokens to try to add.

    This is a L{ShapedConsumer} with a little bit of magic to provide for
    the case where the consumer it wraps is also a C{Transport} and people
    will be attempting to access attributes this does not proxy as a
