=======================================================================
RTI Connext DDS XML App Creation

Define a service as a set of data-oriented interfaces.

The 'square' service has two interfaces:
	- a publication (output) of squares
	- a subscription (input) of squares 

These interfaces can be composed with other service interfaces 
(if desired) to define component interfaces.
