<PRE>class Actors
</PRE>
<P>
Provides handy helper methods to create pooled actors and customize the underlying thread pool.
Use static import to be able to call Actors methods without the need to prepend them with the Actors identifier.
<pre>
import static org.gpars.actor.Actors.*
Actors.defaultActorPGroup.resize 1
def actor = actor {* react {message ->
println message
}* //this line will never be reached
}.start()
actor.send 'Hi!'
</pre>
All actors created through the Actors class will belong to the same default actor group and run
on daemon threads.
The DefaultPGroup class should be used when actors need to be grouped into multiple groups or when non-daemon
threads are to be used.
