Treehouse Techdegree Project #1 - Random Quote Generator

Each quote should have the following properties:

• A quote property which contains a string: the text of the quote to display on the page.
• A source property which contains a string identifying the creator of the quote.
• An optional citation property which contains a string identifying the publication the quote appears in.
• An optional year property which contains a number identifying the date of the quote.

• selects a random quote object from the quotes array
• returns the randomly selected quote objects

• printQuote calls the getRandomQuote function and stores the returned quote object in a variable.
• printQuote constructs a string using the different properties of the quote object using the following HTML template:

<p class="quote"> [quote here] </p>
<p class="source"> [source here]
  <span class="citation"> [citation here] </span>
  <span class="year"> [year here] </span>
</p>

• printQuote doesn't add a <span class="citation"> for a missing citation or a <span class="year"> if the year property is missing.
• printQuote displays the final HTML string to the page. You can use the following JS snippet to accomplish that: document.getElementById('quote-box').innerHTML

• Add more properties to the quote object. For example, a tags property could include a list of "tags" like -- "humor", "business", "politics" -- to categorize each quote.
• Randomly change the background color of the page, when the quote changes
• Don't display a random quote more than once until ALL quotes from the array have been displayed.
• Refresh the quote after a set amount of time. For example, every 30 seconds, make a new quote appear. (You can use the setInterval() or setTimeout() method to do this -- see the links in the Project Resources listing.)
