Randomization

[jugglinmike]

The Director's role in all this might be easier to understand if it did
something interesting. We'll start by having it show the Mole at a random time

• mole.js
  • Define a method called scheduleShow that accepts a delay value
    as its only argument. It should show the Mole using window.setTimeout
    and the delay argument.
• director.js
  • Replace the call to show in the Director's constructor with a call to
    scheduleShow. Use the Math.random function to make it a little
    unpredictable. Remember: scheduleShow uses window.setTimeout, and that
    expects the delay to be in number of milliseconds. Math.random returns
    a random number between 0 and 1, so you'll have to write a small formula to
    make the "right" random number.
