This modifier determines the number of nearest neighbors of each particle within a given cutoff radius (the coordination number).
The modifier stores its results, i.e. the number of neighbors each particle haa, in the Coordination
particle property.
In addition to determining the number of neighbors of particles, the modifier also computes and displays the radial pair distribution function (RDF) up to the given cutoff distance.
The maximum distance between pairs of particles to be considered neighbors.
