  Description     : A node port of python's os.walk

node-walk is a Node.js walk implementation.

This is somewhat of a port python's os.walk, but using Node.JS conventions.

 * EventEmitter
 * Asynchronous
 * Chronological (optionally)
 * Built-in flow-control
 * includes Synchronous version (same API as Asynchronous)

As few file descriptors are opened at a time as possible. This is particularly
well suited for single hard disks which are not flash or solid state.

node-walk is required for OpenLayers 3 (#774561).
