Example: Image Processing

[ax3l]

We should add an additional example in example/ that is non-CUDA-SDK and supports the full range of Alpaka execution strategies (add element layers, allow arbitrary number of threads in both blocks and thread level) so it can be run in travis with a few (stay 2-4) physical threads in less then a minute.

One example would be:

• the standard edge detection/skeletonize/sobel (example) algorithm with stencils on an image of ~400x200 px
• some mandelbrot example

@vincentridder could be interesting for you.

there are examples for a soble-filter and mandlebrot in the cuda sdk. Porting and tuning them would be easier.

offline discussion: the sdk examples have quite some "heavy" gl dependencies and are implementing "several stages" of parallelism instead of a simple, "ideal solution" others can copy from.
