1. Build a function that gets called by the onload event.
2. In that function, create an array that stores a color in each of its elements.
3. Then write a for loop that creates an option element for each color in the array.
4. Finally, use innerHTML and the string you just created to set the options for the select box

Colors:	--SELECT A COLOR--

EXTRA CREDIT: Search the internet to see if you can figure out how to get the selected item from the select box with JavaScript.
Write the code in a function that gets called when the button is clicked.
