/**
* @class EC_Schedule
*
* @brief Test the EC scheduling test
*
* The EC can be used in conjunction with the scheduling service
* to analyze the schedulabity of a system and compute priority
* assignments that guarantee the correct behavior of it.
* Most of the work is actually done by the scheduler (as it
* should be), the event channel simply plays two roles:
* 1) Feed the scheduler with the dependency information between
* consumers and suppliers based on their QoS requirements,
* subscriptions and publications.
* 2) At run-time use the scheduler information to dispatch the
* events at the right priority.
* The current version only verifies the first role.
