* classes. They are in here because they are either needed globally or are inherently universal
* to the application.
*
* Note that just because a class might be used by both WM and SysUI does not necessarily mean that
* it should go into this module. If WM and SysUI might need the class for different purposes
* or different semantics, it may make sense to ask them to supply their own. Something like
* threading and concurrency provide a good example. Both components need
* Threads/Handlers/Executors, but they need separate instances of them in many cases.

* Please use discretion when adding things to the global scope.
