add features to TikzGenerator
* Add config to choose if all or only alive trajectories are drawn * Draw walking direction in Tikz * create nodes for pedestrian instead of circles. Each pedestrian node has a name 'ped_ID' to reference the node in tikz. * add named coordinate at Centroid for all scenario elements: * source: (src_<ID>) * target: (trg_<ID>) * absorbingArea: (absorb_<ID>) * obstacle: (obs_<ID>) * stairs: (str_<ID>) * measurementArea: (mrmtA_<ID>) * add style classes: * trajectory: i.e. thickness * pedestrian: default color * ped_circle: defines shape of circular pedestrians (not for groups) * selected: style for selected pedestrian * group: styl (all) groups.
