Assignment:
* Create a new document called madlib.html.
* Write or find your own poem or story. Make sure to cite sources
if you use someone else's work.
* Before you begin prompting for input, explain to the user
what is going to happen.
You may wish to show them an example of the text and indicate
which words can be changed.
* You may use only LOCAL variables.
* You must use a function which prompts the user for
at least 3 inputs for your mad lib.
Before the input begins, tell the user how many prompts to expect.
* You must then pass those inputs to another function which
writes the output to the page.
* All output to the page must be written using JavaScript.
