Corrected another error discovered by Andrei Bondar in which 

the critical property (e.g., L for transistors) is required to
match exactly between devices in order to allow the additive
property (e.g., W for transistors) to be summed.  The critical
property should match if all values are within the slop value,
for floating-point values.  Note:  The implementation is still
not rigorous, as the saved critical value may shift from
device to device;  so comparing, e.g., 1.00 to 1.01 to 1.02 to
1.03, etc., can find that all individual comparisons are within
the slop value even though the slop is exceeded across all values.
