* @brief The main program

* Opens the camera and reads pictures as fast as possible
* Makes a debayering of the image
* Writes the debayered image to a buffer which can be read by
* TCP clients on Port 8111. Several concurrent clients are allowed.
* The simplest streaming video client looks like this:
*
* nc 192.168.1.10 8111 | mplayer - -demuxer rawvideo -rawvideo w=376:h=240:format=bgr24:fps=100
*
* Writes every 10th picture to a .jpg file in the Web Server Directory
