TO DO
- Sometimes ( or only with optimized compilin' with MS C++6.0 it cannot find the nearest Neuron !!!??) qSOM2d :: GetWinner isn't able to find minima and the result of a undefined return, would be a page fault. Now this problem is solved by a default setting of this return to 0, but this isn't obviously a solution - and not absolutely a mathematical - Another interesting problem is that this bug only occures with MS C++ and not with g++ and only in some special times. The random number generator is being initialized with srand(time(NULL)), could this be the solution ???? Have fun while searching this crazy bug !!
- in nVec.cpp : The pointer to data has to be checked and in case an errror has to be thrown
