  Description     : walk the ast with references to parent nodes

 This module is a faster version of
 [falafel](https://github.com/substack/node-falafel)
 that only does ast walking and `.parent` tracking, not source transforms.
 # example
 var astw = require('astw');
 var deparse = require('escodegen').generate;
 var walk = astw('4 + beep(5 * 2)');
 walk(function (node) {
    var src = "">    console.log(node.type + ' :: ' + JSON.stringify(src));
 });
