Comments

All values must have the same dimensionality but may have different units (e.g., all values could be flows, but some in units of cms and others in cfs). Similarly, all weights must have the same dimensionality. Currently, if the dimensionality of the values or weights involves temperature, then all items in that list must have identical units (e.g., it would not be permitted for some values to have units of Celsius/meter and others to have units of Fahrenheit/meter).
