// An example of setting and reading some bits. Note that operator[]
// goes from the least-significant bit at 0 to the most significant
// bit at size()-1. The operator<< for dynamic_bitset prints the
// bitset from most-significant to least-significant, since that is
// the format most people are used to reading.
//
//  The output is:
//
//  11001
//  10011
