Example Using While Loops - Using Coding 101 - Episode 02

/* Example on what was learned on Coding 101 - Episode 02 - While Loops
* I made the example trying not to use "advanced" concepts, and only what the episode was trying to teach.
*
* The first thing I think when talking about while loops is animations and games. And for games we need
* at least some ifs... so animation its a cool demostration for this example.
*
* The most useful thing in the example, I think is the use of the While loop to make different kinds of
* animations, also the border can be more complicated once we know about loops.
*
* This was built with the knowledge learned from Episode 01 and 02 and my last Example: https://gist.github.com/squareiguana/9113733
*
* Arrays are mentioned on the code that Lou provided with a link to MSDN, I didn't include them in this example
* because I think that will be the topic of a future episode.
*
* I'm going out of my way to use only the simple concepts, this definitely needs a refactor once they go into
* more "advanced" topics like methods, functions, classes, constants, ifs, for loops, etc. maybe I'll do
* a refactor or several, after some of those topics to show a more cleaner code.
*
* Definition of Refactor: To rewrite existing source code in order to improve its readability, reusability or
* structure without affecting its meaning or behaviour.
