/**
* This preference represents the default log level for the Bluetooth stack
*
* The default log level is captured and held in an Android Log Framework log tag, using "bluetooth"
* as the tag name. The Log framework does not provide methods to directly write a log tag value,
* but instead leverages special system properties to hold the value of a log tag.
*
* This preferences aims to keep the selection in sync with the currently set log tag value. It
* writes directly to the system properties that hold the level associated with the bluetooth log
* tag. It leverages the Log.isLoggable("bluetooth", level) function to discern the current value.
* The default level is INFO.
*
* This value is read once at start of the Bluetooth stack. To use a new value once setting it, be
* sure to turn Bluetooth off and back on again.
