-// Similar to std::bitset, this is a class which encapsulates a bitset, i.e.
-// using the set bits of an integer to represent a set of integers.  Like that
-// class, it acts like an array of bools:
-//     BitSet32 bs;
-//     bs[1] = true;
-// but also like the underlying integer ([0] = least significant bit):
-//     BitSet32 bs2 = ...;
-//     bs = (bs ^ bs2) & BitSet32(0xffff);
-// The following additional functionality is provided:
-// - Construction using an initializer list.
-//     BitSet bs { 1, 2, 4, 8 };
-// - Efficiently iterating through the set bits:
-//     for (int i : bs)
-//         [i is the *index* of a set bit]
-//   (This uses the appropriate CPU instruction to find the next set bit in one
-//   operation.)
-// - Counting set bits using .Count() - see comment on that method.
