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
The allTests Makefile target does now create the ara-sim binary
Fixed bug in node placement.

The placement was done in init stage 4 but the radios already read and
saved their position in stage 2. This lead to the situation that the
radios would still think they where at another position so they
processed packets which could not have been received by them.
Any existing LD_LIBRARY_PATH is now correctly used during build

I think the issue was that the g++ command indirectly used the
LD_LIBRARY_PATH which has been set in the Makefile without expanding
Any shell variables. I'm not quite sure how the internals work but it
seem sto run now..

Fixes #57
Can now build everything with make HEADLESS=TRUE
Added high traffic configuration xml
Update README.md

added remark on building ara-sim headless
Added a new Makefile target cleandep
Merge branch 'develop' into routeFail
