+/**
+ * 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 first-come-first-serve 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
