FUNCTION: discoverDevices
DATE: 18/10/2015
INTERFACE: bool discoverDevices()
RETURNS: If any of the discover devices/reader API calls fail, false is returned. Otherwise on succession, true is returned.
NOTES: Calls the SkyeTek API to check if any USB devices are plugged into the host machine. If there are devices found, the
next API call is to look for RFID readers. If the reader happens to be a serial device, the function will get the
appropriate baud rate. If none of the API calls fail, a succeed dialog box is printed to the console.
