/**
\file mainClient.cpp

This file is an example of how to implement the slsDetectorUsers class 
You can compile it linking it to the slsDetector library

gcc mainClient.cpp -L lib -l SlsDetector -lm -pthread

where lib is the location of libSlsDetector.so
gcc mainClient.cpp -L . -l SlsDetector -lm -pthread -o users
