/**
* Registers which apk was installed on which device.
* <p/>
* The goal of this class is to remember the installation of APKs on devices, and provide
* information about whether a new APK should be installed on a device prior to running the
* application from a launch configuration.
* <p/>
* The manager uses {@link IProject} and {@link IDevice} to identify the target device and the
* (project generating the) APK. This ensures that disconnected and reconnected devices will
* always receive new APKs (since the APK could be uninstalled manually).
* <p/>
* Manually uninstalling an APK from a connected device will still be a problem, but this should
* be a limited use case.
* <p/>
* This is a singleton. To get the instance, use {@link #getInstance()}
