-// This is a small library for implementing common bit vector utilities,
-// namely:
-//
-//  - popcount : The number of bits set in an unsigned int
-//  - ctz : The number of trailing zero bits in an unsigned int.
-//          Must be called with a value that has at least 1 bit set.
-//
-// These methods will typically use instrinics when available, and have a
-// generic fallback in the event that the instrinic is not available.
-//
-// If clz (count leading zeros) is needed, it can be added when needed.
