Detailed Description

This is a 'bitvector' (really, a variable-sized bit array), optimized for the case when the array is small.

It contains one pointer-sized field, which is directly used as a plain collection of bits when possible, or as a pointer to a larger heap-allocated array when necessary. This allows normal "small" cases to be fast without losing generality for large inputs.
