<div class="block">Main class starting any game, contains main(). Apart from that, this class manages all
non-logical functionalities which should be hidden from a game designer like:
<ul>
<li>Setting up windows, panels, buttons, action callbacks, ...
<li>Reading keyboard inputs
<li>Redrawing game window if necessary
<li>managing the game time and calling the appropriate <a href="../gameobjects/GameObject.html" title="class in gameobjects"><code>GameObject</code></a> or <a href="../playground/Playground.html" title="class in playground"><code>Playground</code></a>
methods periodically, at every time step of the game.
</ul>
There will normally never be a need to modify this file, a designer/game programmer should always
redefine the <a href="../gameobjects/GameObject.html" title="class in gameobjects"><code>GameObject</code></a> and <a href="../playground/Playground.html" title="class in playground"><code>Playground</code></a> classes and implement new functionality
there. To make a long story short<br></div>
