added first own debug feature: ray.d 

(which doesn't seem helpful)
removed compiled files
tried adding lens possition in same fashion

but ends up in segfault -> do I access sample.lensU in a wrong way?
initialized variable, solved segfault
Added own struct that captures data of all samples
added second, third origin, renamed Lxyz to rgb
added example for testing to repository
dumping now images from own sd stuff
soring now samples before dumping content

also some renaming, removing of obsolete code and files
