<hr><a name="_details"></a><h2>Detailed Description</h2>
The CamStream main application class.
<p>
<p>
This class is the main object for the CamStream application. It does the following:<ul>
<li>creates the canvas, loads widgets;<li>determines available image file formats;<li>stores and retrieves user settings;</ul>
The configuration is stored as an XML document. The structure still has to be defined fully, and is partially defined by sub-elements.
