Trouble compiling and missing license

Interesting repo :) 

I tried to include runy your NS3-HelperScripts/examples/MobilityExample/custom-mobility-model.cc, but I am missing the #include "ns3/console-color.h" which is not part of the ns-3 repo. 

Moreover, your repo is missing a license file...maybe you can add one ;) e.g. CC-BY-4.0 License  or whatever...
