currently, it is pretty expensive to compute fractal dimension.

in the test neuron

get fractal dimension ...                                            
 28.322377 seconds (681.63 M allocations: 20.345 GiB, 9.42% gc time) 
fractalDimension = 1.3603973145963741

current implementation is based on nodes, we can change to branch based implementation. we can skip the branches that have starting point closer or farther than r +- path length .
