[ENHANCEMENTS]
Unset the need for channel locking if only worker riding the channel.
There are 8 data channels in MCE. Basically, a worker will obtain a
lock only when sharing the data channel with another worker.Updated files_flow.pl, files_mce.pl and files_thr.pl to allow for
many workers for the first task. Updated the synopsis in MCE::Queue.
Synced example listing in Examples.pod with the examples folder.Remove period from summary line.
