Heap Manager

This is the Dragon heap manager interface for Python

Classes 

class BitSet

Bases: object

A Cython class interface for the malloc Bitset library

static attach(space)

destroy()

detach()

dump(title, indent)

dump_to_str(title, indent)

get_bit(idx)

get_num_bits()

static init(num_bits, space)

Initialize the space with a BitSet of size num_bits.

Parameters:
