This class encapsulates many of the commonly used features of Mozilla's preferences-related interfaces into a centralized, reusable class. It traps exceptions, allows you to specify default values for preferences when they don't exist in any preference tree, and keeps code organized by localizing preference manipulation to a single class. The only interfaces not yet supported are nsILocalFile and nsIRelativeFilePref. Feel free to add them if you like. Sample usage is shown in the leading comments.
