Detailed Description

This is a manager class designed to transport information from one thread to an other. The comunication is based in channels, each channel has its own LinkedBlockingQueue to gurantee data consistency. Once you get a channel to eficiently extract the data the darinTo(Collection c) meber is prefered, as it will move the data from the queue to the colection in an atomic action.
