vz walk

DEPRECATED in favour of y-walk

Sample usage:

 
var walk = require('vz.walk'),
    yieldify = require('vz.yieldify'),
    fs = require('fs'),
    exists = yieldify(fs.exists);
 
walk(function*(){
  if(yield exists('foo.bar')) console.log('foo.bar exists!');
  else console.log('foo.bar doesn\'t exist');
});
