 +=====Process=====
 +The general flow of the process (one way of going about it, anyway) can be described as follows:
 +
 +<code>
 +number <- 0
 +loop (endlessly)
 +    if the number is zero
 +        activate/deactivate the four LEDs to represent zero
 +
 +    if the number is one
 +        activate/deactivate the four LEDs to represent one
 +       
 +    if the number is two
 +        activate/deactivate the four LEDs to represent two
 +
 +    ... on and on through the cases for the remaining numbers
 +
 +    strategic delay so you can see the current number
 +
 +    let the number increment by one, but not to exceed fifteen
 +done
 +</code>
