EventosExecutionPlanBase Pull Request 2

- Changed setSequence and start methods of the EventoExecutionPlan base to virtual methods.
- Removed SetSequence and Start methods from the EventoExecutionPlan since it will inherit those methods from the base and since they are virtual they can be overridden.
- As a result of the virtual method the start and set sequence methods can be removed from the eventosamples and test classes
- Fixed small bug with SetSequence using enumerator
- Stopped tracking test results directory
