- set target for movement currently only supported in the modularosm
model, feel free to extend other models by overwriting the default
implementation and create the corresponding merge requests.

Topology fix

Fixes bugs in DefaultTopologyComponent **recalculateLocalView()**:
It now returns a copy of the current position.
Also fixed a bug where it tries to generate edges to nodes not in the graph.

See merge request !32

removed previous 'fix' to AbstractTopology

PositionVector

- support for in-model placement of nodes

- deprecated MovementSupported
- used LocationSensor and LocationActuator
- decoupled nested listener structures used within the old models

actually changed.

implemented by all netlayers
updates MaxPeerCountChurnGenerator to support the interface (default
behavior still triggers the network-layer functions)

Fixed minor error in PositionVector for Lat = Y and Long = X.

JSON Placement for OSM Data

Added a Placement Model for Hosts that takes OSM Input data for real map placement of e.g. infrastructure entities such as AccessPoints at "attraction point" locations.

See merge request !28

fix transition strategy to only fire once an Attraction Point is reached
remove POI limitation for Json-based Attraction Points

(used for #cloudlet-evaluation)

to enable easy filtering for postprocessing without relying on host IDs

enabled direct instantiation of custom attraction points in the XML
config

Merge nr/master-debug into master

Added MaxPeerCountChurnGenerator. A churn model what follows a predefined "trace" that states how many nodes should be in the network. Nodes may be used for multiple times, thus overlays have to ensure to handle such events. The csv file must highlight the time when a churn should start, the length of the churn (used to calculate the inter arrival rate of nodes), and the number of nodes that is to be achieved.
