// This map is lost when the application is closed, or the user is changed.
// An example of a memory entry is the CurrentViewedPage entry.

// Examples of memory entries include:
//	-AppUser (name of user who is signed in)
//	-CurrentViewedPage
//	-StopBuildMyMatches
//	-ViewedModeratorsReadyProgressStatus
