added rails initialization for the various message queue options
. added recognition of existing queue when initializing one (important if there are multiple processes running the models logic)
moved drb location to the gem configuration
moved the definition of the marshalable method registering and copying inside the loop. Why? Each job will unregister its method. If one uses the same method for more than one job, by the 2nd job the method was already unregistered. should not happen
added some comments
