Transforming Code into Beautiful, Idiomatic Python

Notes from Raymond Hettinger's talk at pycon US 2013 video, slides.

/// Calculates elapsed time.
///
/// Typical usage is to construct an instance at the start of an operation,
/// and then call `elapsedTimeInterval()` or `elapsedTimeString()` at
/// the end to determine how much time has passed.

/// The underlying time reference is `mach_absolute_time()`
