Visual Studio default toolset uses 32bit executables for compiling which means that if it uses more than 4GB of memory per instance it crashes. By moving the ConnectivityTracer into a separate compilation unit we can help out the compiler. This also improved compilation times and library size: Old: build time (j8): 48.62 real lib size: 6.2MB New: build time (j8): 41.31 real lib size: 5.0MB
