cpu deconvolution only differs by 30% from reference deconvolution given by Stephan
added page-locking to cuda_memory (TODO: needs to be used inside gpu_convolve and multiviewnative.cu)
refactored cuda_memory, type of Memcpy call is now outside of the class
threw out test_cuda_memory for now
adopted cuda_memory
cuda memory fulfills requirements, interface standing and implemented to gpu_convolve
gpu convolve seems to be broken due to adaptation of cuda_memory
fixed compiler warnings of gcc 4.4.*; forgot to add option to cuda_memory that memory placed on device is larger than input array, so cufft has some room to play in native mode
