Debug any JavaScript object's method invocations.

object.debug.js

/**
 * author: "Joe Johnson (say2joe@gmail.com)"
 * Debug any JavaScript Object by inserting this code into your main JavaScript file.
 * After initiating debugging on an object (ex. myObj.debug();), your console will
 * log the name of a [named] function and its execution time. This helps when tracing
 * the stack method calls with many objects and method calls.
 * Note: this most likely only works for WebKit-based browsers supporting fn.name.
 * Also, you may copy-paste this into console before running any event-based logic.
