Detailed Description

A BitSet to replace java.util.BitSet. Primary differences are that most set operators return new sets as opposed to oring and anding "in place". Further, a number of operations were added. I cannot contain a BitSet because there is no way to access the internal bits (which I need for speed) and, because it is final, I cannot subclass to add functionality. Consider defining set degree. Without access to the bits, I must call a method n times to test the ith bit...ack!

Also seems like or() from util is wrong when size of incoming set is bigger than this.length.

This is a C++ version of the Java class described above, with only a handful of the methods implemented, because we don't need the others at runtime. It's really just a wrapper around vector<bool>, which should probably be changed to a wrapper around bitset, once bitset is more widely available.
