In massProps: Calculate Mass Properties and Uncertainties of Tree Structures

#' Mass Properties and Uncertainties Table from SAWE Paper No. 3360

#'   Uncertainty in Mass Properties Engineering.” In 64th Annual International
#'   Conference on Mass Properties Engineering, 123–60. Society of Allied Weight
#'   Engineers.

#'   Note: the results for combined mass properties and uncertainties in the
#'   published example are accurate only within approximately 0.2%.
