+====== Description ======
+This is a collection of fuzzy-based nodes which do direct arithmetic comparisons:
+^ symbol ^ description ^
+| ''<'' | less than |
+| ''<''''='' | less than or equal to |
+| ''=='' | equal to |
+| ''>='' | greater than or equal to |
+| ''>'' | greater than |
+| ''!='' | not equal to |
+====== Constraints ======
+  * Minimum number of child-nodes: 2
+  * Maximum number of child-nodes: 3
+====== Calculus ======
+If the compare node has just two child-nodes then the calculation is straight forward and is exactly as stated in the description and the node calculates to true (+1) or false (-1) if both child-nodes have valid values, otherwise it will calculate to undetermined (0).
+^ operator ^ Value<sub>1</sub> ^ Value<sub>2</sub> ^ output ^
+| ''<'' | 3 | 4 | true (+1) |
+| ''<'' | 4 | 4 | false (-1) |
+| ''<'' | 4 | 3 | false (-1) |
+| ''<''''='' | 3 | 4 | true (+1) |
+| ''<''''='' | 4 | 4 | true (+1) |
+| ''<''''='' | 4 | 3 | false (-1) |
+If the compare node has three child-nodes then the third node is used to define a fuzzy curve to transition the calculation.  In general (the ''!='' is opposite) the second node defines the true point on the fuzzy curve and the third point defines how far from the second node the false point is (the transition distance).
+Note that in this mode ''<'' and ''<''''='' are functionally equivalent as is ''>'' and ''>=''.
+^ operator ^ Value<sub>1</sub> ^ Value<sub>2</sub> ^ Value<sub>3</sub> ^ output ^
+| ''<'' | 3 | 4 | 2 | true (+1) |
+| ''<'' | 4 | 4 | 2 | true (+1) |
+| ''<'' | 4.5 | 4 | 2 | +0.5 |
+| ''<'' | 5.0 | 4 | 2 | 0 |
+| ''<'' | 5.5 | 4 | 2 | -0.5 |
+| ''<'' | 6 | 4 | 2 | false (-1) |
+| ''=='' | 2 | 4 | 2 | false (-1) |
+| ''=='' | 3 | 4 | 2 | 0 |
+| ''=='' | 4 | 4 | 2 | true (+1) |
+| ''=='' | 5 | 4 | 2 | 0 |
+| ''=='' | 6 | 4 | 2 | false (-1) |
