 * Styles that are defined in {@link SharedPreferences} are preserved. If
 * none are defined, the GPS location provider is assigned the red style
 * and the network location provider is assigned the blue style. The
 * passive location provider is not assigned a style, as it does not send
 * any locations of its own. Other location providers are assigned one of
 * the following styles: green, orange, purple. If there are more location
 * providers than styles, the same style (including red and blue) can be
 * assigned to multiple providers. The mapping is written to 
 * SharedPreferences so that it will be preserved even as available
