 This function is related to the PDF through

 (see @ref{Shape-related morphs}). A partial RDF @math{R_i(r)} is defined such that @math{R_i(r)dr} gives
 the number of atoms in the spherical shell bounded by @math{r} and @math{r + dr} centered at atom @math{i}.
 The total RDF for an atomic system is the average of the partial RDFs of each atom in the system
