OSM to UE4 data parser

TODO: comunication between workers:

• worker1 needs some nodes, ask master where to find them
• master answers - worker2,3 and 4
• worker1 asks worker2, 3 and 4 for the nodes
• etc...

dependencies

• node-ipc - communication between workers
• node-expat - parse incomming stream of XML data
• log-update - makes persistant progress bars possible in CLI
• chalk - colors for CLI logs

requirements

• big XML file extract from Osmosis
• redis instance installed locally (used for caching <node> elements)
