A TrajectoryReader is the counterpart of the FootStepProcessor. Output file assumptions: The TrajectoryReader assumes that the first row of the output is the headline and that there exist certain columns named: (id or pedestrianId) [mandatory], simTime [mandatory], startX [mandatory], startY [mandatory], endX [mandatory], endY [mandatory], targetId [optional] and groupId [optional]. The order of the rows (expect for the first row / header) can be arbitrary. Columns has to be separated by TrajectoryReader#SPLITTER and OutputFile#headerProcSep.
