Started to write the RoutingTablePersistor (work in progress)
The RoutingTableDataPersistor does now save the routing table data as binary to file
Added FIXME comment for inefficient procedure
Fixed issue with the filenames for the routing table persistence

Also all files generated by RoutingTableDataPersistor do now have the
file extension *.rtd (for routing table data)
The endianess if no longer strongly defined but the systems byte order is used

This works because the evaluating python script is expected to be run on the same
machine and python can natively handle the same byte order
Increased the time resolution for the routing table data to 2/sec
Merge branch 'routingTableStats' into develop

Fixes #50
