/**
* The registry maintains a database of persistent settings for an application.
* The settings database is organized in two groups of three layers each. The
* system-wide settings group contains settings information pertaining to all
* users on a system. The per-user settings group contains settings affecting
* that user only.
* Each settings group contains a desktop layer, which comprises the settings
* which affect all FOX programs, a vendor layer which holds settings that
* affect all applications from that vendor (e.g. a application-suite), and
* an application layer which holds settings only for a single application.
* The vendor-key and application-key determine which files these layers come
* from, while the "Desktop" key is used for all FOX applications.
* Settings in the system-wide group are overwritten by the per-user group,
* and settings from the "Desktop" layer are overwritten by the vendor-layer;
* vendor-layer settings are overwritten by the application-layer settings.
* Only the per-user, per-application settings ever gets written; the layers
* in the system-group only get written during installation and configuration
* of the application.
* The registry is read when FXApp::init() is called, and written back to the
* system when FXApp::exit() is called.
