-/**
- * Please refer to TEP 108 for more information about the components
- * this application is used to test
- *
- * This application is used to test the functionality of the
- * FcfsArbiter component developed using the Resource
- * interface. Three Resource users are created and all three request
- * control of the resource before any one of them is granted it.
- * Once the first user is granted control of the resource, a timer
- * is set to allow this user to have control of it for a specific
- * amount of time. Once this timer expires, the resource is released
- * and then immediately requested again. Upon releasing the resource
- * control will be granted to the next user that has
- * requested it in FCFS order. Initial requests are made
- * by the three resource users in the following order<br>
- * <li> Resource 0
- * <li> Resource 2
- * <li> Resource 1
- * <br>
- * It is expected then that using a round robin policy, control of the
- * resource will be granted in the order of 0,2,1 and the Leds
- * corresponding to each resource will flash whenever this occurs.<br>
- * <li> Led 0 -> Resource 0
- * <li> Led 1 -> Resource 1
- * <li> Led 2 -> Resource 2
