Valid dBm ranges should *not* be mentioned in the documentation. Manufacturers should be able to produce devices which can detect signal strengths with arbitrary sensitivity rather than being forced to restrict strengths to a certain range. Adds a reference to WifiManager.calculateSignalLevel(), an often-useful method to convert these RSSI values into an absolute signal level that can be displayed to a user as the signal strength.
