Inspect functions that are part of a promise chain

inspect.js

// Uses underscore.js to wrap a function and upon calling
// prints the function source and the argument.
// Useful for debugging chains of promises.
// USAGE
// var myfunction = function(argument) {...};
// myfunction = inspect(myfunction); // myfunction is now instrumented

var _ = require('underscore');
var util = require('util');
var inspect = function(fnToInspect) {
  return _.wrap(fnToInspect, function(fn, resolvedPromise) {
    console.log('-------------------------------------------------------------');
    console.log('FUNCTION');
    console.log(String(fn));
    console.log('.  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .');
