CppND-ProjectCapstone_BinaryBandit81

Program to monitor if a subwaytrain is currently at a station for the complete subway in Munich. The Code is derived from https://github.com/udacity/CppND-Program-a-Concurrent-Traffic-Simulation

What it does

1. Open the subwaystation map '/data/mvg_subwaystations.png'
2. read subwayline from file '/data/lines.csv'
3. read a stationlist from file '/data/stations.csv'
4. start a thread for every subwaystation
5. in every thread:

• request the current departures via http with a request like this: https://www.mvg.de/api/fahrinfo/departure/de:09162:130?footway=0
• check if a subwaytrain is at the stationdraw a colored dot on the map at the station location
• remove all trains from station that have left the station
