MusolesiMobility: initial version from https://github.com/leonardomaccari/inet-privacy, 6ca812cc5d
MusolesiMobility: Added [General] section to the musolesi-tests.ini and a little bugfix
MusolesiMobility: Obstacle Control removed from MusolesiMobility; changed to work without LineSegmentsMobilityBase changes

- obstacles support removed (it was very rudimentary in the first place)
- setInitialPosition() split into two functions
- girvanNewman removed (did not work)
MusolesiMobility: code formatting and comments
MusolesiMobility: further cleanup

- contraint area: INET now uses min,max instead of pos+size
- Removed some useless functions and variables,
- memory allocation by malloc is replaced with operator new[]
MusolesiMobility: Memory allocation and deallocation fixed, more useless code removed.
MusolesiMobility: cosmetics: copyright headers, space changes, ev->EV, etc.
MusolesiMobility: GirvanNewman support really removed
MusolesiMobility: camelCase renaming
Musolesi Mobility: Adjacency matrix removed. It was only needed for Girvan-Newman algorithm
MusolesiMobility: Made some renaming and comment changes to stay consistent with the notions used in Musolesi's paper
MusolesiMobility: Matrix a was useless, "refresCommunities" typo
MusolesiMobility: Proportional targetchoice renamed to probabilistic
MusolesiMobility: The exit condition simplified in the probabilistic case
MusolesiMobility: Comments and code formatting
MusolesiMobility: There is no need for numberOfMembers because we use std::vector
