	Increasing to the complexity is that some properties may change values due to a treatment. Diameter won't change by a treatment, but number of stems will. A property that may have different values before and after treatments also has a residual property (and a residual array property), e.g. <tt>Stems</tt> and <tt>StemsResidual</tt>.
