[BonnMotion] Draft for Bonnmotion

Thu Apr 18 12:13:20 CEST 2019

Dear Noah,

in most cases you can use the command line to get additional information
about the parameters used by the implemented models. For the
DisasterArea model the following command will print the usage help:
      bm -hm DisasterArea

In addition, a sample perl script is included
(doc/da_example/sample.pl). Take note, that you can add multiple
obstacles by chaining multiple obstacle parameters.

Best,
 Alexander

I would like my node to inherit the attribute of whatever group it meets and each group should consist of 5 nodes each (say for 10 nodes, it will be 2 groups of 5 nodes). -n runs well for 10 nodes and 6 speed and 12 speed but when I increase the nudes from 20 all through to
