Bases: QObject
A Timer that checks whether host app is still alive.
This checks whether the Fusion process is still active at a certain interval. This is useful due to how Fusion runs its scripts. Each script runs in its own environment and process (a fusionscript process each). If Fusion would go down and we have a UI process running at the same time then it can happen that the fusionscript.exe will remain running in the background in limbo due to e.g. a Qt interface's QApplication that keeps running infinitely.
Warning
When the host is not detected this will automatically exit the current process.
