Detailed Description

Composite test application for I3.

This tests the ability of I3 to realize service composition in which the receving node decides the routing of a packet. First, all nodes insert their own trigger. Then, node 0 creates an packet containing an empty sentence (""), and sends it to I3 with an identifier stack containing the triggers of service nodes 1, 2, 3, 4 and then node 0. I3 then routes the packet to each of those triggers in that order. Each service node adds some words to the sentence ands sends it back to I3 with the same identifier stack it received. When it returns to node 0 it displays the sentence it received and starts again.
