========

Full Python implementation of a bitarray.

Memory optimization: It packs 32 or 64 bits on a float. Depending on the platform.

Usage:

    MAX = 2^^32

    ba = BitArray(MAX, initialize=1)

    for n in xrange(2, MAX, 2):

        ba.reset_bit(n)

    

    ba.set_bit(120)

    

    if ba.get_bit(120):

        pass

Sample usage on pysieve.py
