Kernel focus

Tried to focus the kernel on the cluster in dens areas. I used the sum of the previous weights to approximate the the current one what turned out inappropriate. Any further implementation would complicate the code unnecessarily.
The results improved noticeably by using the scale or dimensions of gamma.
I also implied the objects transformation in space in the construction/computation of gamma. It might be better to imply it rather in the verification step and not use it in gamma.
