Add configuration file to read CLASS parameters

This commit changes the parameters reading. It introduces
getopt to read input parameters from command line and it
uses a configuration yaml file to read the input parameters
for the network, the map and the cameras.

This commit fixes a bug in message sending to the aggregator.
