In many cases, the combining function is simple\narithmetic sum; in other cases (e.g., mass properties), the\ncombiner may involve other information such as the geometric\nrelationship between parent and child, or statistical relations\nsuch as root-sum-of-squares (RSS). This package implements a\ngeneral function for such problems. It is adapted to specific\nrecursive computations by functional programming techniques;\nthe caller passes a function as the update parameter to\nrollup() (or, at a lower level, passes functions as the get,\nset, combine, and override parameters to update_prop()) at\nruntime to specify the desired operations. The implementation\nrelies on graph-theoretic algorithms from the 'igraph' package\nof Csárdi, et al.
