works.

In this release:
- color segmentation utilizing a lookup table
- calculating the region code
- data structures for images (PPM implemented), histograms, 
  region list

- interface to image sources, implemented for cpia webcams and
  compatible video4linux devices
- basic widget to display images
- interface to reinforced learning algorithms
- c-means clustering of multi-dimensional classified data using
  augmented states to auto-initialize the centers 
- automatic calibration of colors with a simple GUI-tool

CONSTRAINTS
- CWebcam tested only with Terratec(tm) TerraCam USB
- CImageWidget needs a screen with 32bpp and a color-depth of 24bits
  with the following bit order to run (try to set X to a true-color
  32bpp/bit mode): 00000000 rrrrrrrr gggggggg bbbbbbbb (0 means unused)
- calibrate and main fixed to shift the rgb-values by 2
- video device at /dev/video0

KNOWN ISSUES
- multi-thread implementation (calibration tool) is still unsafe.
