Description

Pairs is a process whose output is always the sum of its previous two inputs.

Two inputs are needed before any output is produced but that, thereafter, one output is produced for each input.

Channel Protocols

Input Channels
in	java.lang.Number	The Channel can accept data from any subclass of Number. All values will be converted to ints.
Output Channels
out	java.lang.Integer	The output will always be of type Integer.
