Changed the name of this wrapper to be more accurately named.  This is a wrapper for the java.util.concurrent.ScheduledExecutorService to implement the commonly used threadly interface SubmitterSchedulerInterface (so that if you desire you don't need to use threadly's thread pool implementation).
Fix for IllegalArgumentException if expected parallism is > the max thread count.  There is no need to force the parallism to be lower than the thread count (although it does have limited value)
