swarm-lab/Rvision: Rvision 0.6.0

New features We now have a changelog (yes, I know, finally). A large portion of the code base has been rewritten for improving performance and facilitating code maintenance (hopefully). In-place operations have been reworked to allow for saving results in target images for more flexibility while maintaining performance. GPU support has been added wherever possible. Stupid-fast mode enabled on compatible hardware :-) An experimental dynamic queuing system operating on a separate thread has been introduced to allow for reading frames in parallel with image processing on the main R thread. New, hopefully more useful vignettes have been added. More OpenCV functions are now accessible through Rvision (e.g., histogram equalization). Minor improvements and fixes The documentation has been fixed/improved in several places. Minor bug fixes here and there
