bugfix: cudaMemcpy DeviceToHost - out of bounds
minor changes, everything works now
moved identification of exemplars to ap.cu, however, theres currently always the warning that the algorithm did not converge, even if the results are correct, check for conv. conv == 0
outermost loop running on GPU, too
changed *dec to **dec
removed calculation of exemplars and see if finished back to apcluster.cpp.cu -> results match with the originial apcluster.c
removed (at least now) unnecessary conversion checks, now we have one loop left that is responsible for calculating the clusters -> add to kernel
