/*
* Contains some bit manipulation helpers.
* A class to provide efficient manipulation of bitsets.
*
* DO NOT USE: std::bitset<32> or std::bitset<64> preferred
* Consider using std::bitset<32> or std::bitset<64> if all you want is a class to do basic bit
* manipulation (i.e. AND / OR / XOR / flip / etc). These classes are only needed if you want to
* efficiently perform operations like finding the first set bit in a bitset and you want to
* avoid using the built-in functions (e.g. __builtin_clz) on std::bitset::to_ulong.
