Detailed Description

Use spring analogy - attract neighbouring cells according to the distance of their cell indices.

Maximum jump of cell indices. Is fraction of number of cells maxCo 0.1;

Limit the amount of movement; the fraction maxCo gets decreased with every iteration. freezeFraction 0.9;

Maximum number of iterations maxIter 1000;
