Message:

Lots of for loops now count in reverse order where it does not matter, some 3 -> NDIM

for(i=0;i<var;i++) is slower than for (i=var;i--;) if the order of the i's is not important (note: i-- is also a value and it stops when on i == 0 automatically)
in builder.cpp there were some remnant 3 actually meant to be NDIM
