Neuron tree topology equations can be split into two subtrees and solved
on different processors with no change in accuracy, stability, or
computational effort; communication costs involve only sending and
receiving two double precision values by each subtree at each time step.
Application of the cell splitting method to two published
network models exhibits good runtime scaling on twice as many
processors as could be effectively used with whole-cell balancing.
