// There are three functions defined here:
//
// log (message)
// Logs a message. Every second, all logged messages are displayed
// in an alert box. This saves you from having to hit Return a ton
// of times as your script executes.
//
// inspect (object)
// Logs the interesting properties an object possesses. Skips functions
// and anything in CAPS_AND_UNDERSCORES.
//
// inspectValues (object)
// Like inspect(), but displays values for the properties. The output
// for this can get very large -- for example, if you are inspecting
// a DOM element.
