* Task worker in Haxe
* Connects PULL socket to tcp://localhost:5557
* Collects workloads from ventilator via that socket
* Connects PUSH socket to tcp://localhost:5558
* Sends results to sink via that socket
*
* See: http://zguide.zeromq.org/page:all#Divide-and-Conquer
*
* Based on code from: http://zguide.zeromq.org/java:taskwork
*
* Use with TaskVent.hx and TaskSink.hx
