Update of /cvsroot/tinyos/tinyos-2.x/apps/tests/TestArbiter/TestImmediateArbiter
In directory sc8-pr-cvs10.sourceforge.net:/tmp/cvs-serv29909/apps/tests/TestArbiter/TestImmediateArbiter

Added Files:
      Tag: tos-2-resource-pm-eval-cand
	Makefile TestArbiterAppC.nc TestArbiterC.nc 
Log Message:
Creation of an Arbiter that only provides the immediateRequest interface rather than the standard Resource one.  Next step is to have an arbiter that has both as well as possibly a ResourceController interface.  Having all these different types of arbiters lends itself to performing more a accurate evaluation of each type.

 * Once the first user is granted control of the resource, a timer

 * <li> Resource 0
 * <li> Resource 2
 * <li> Resource 1
 * 
 * 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.
