/*-----------------------------------------------------------------------------------------------------------------------------------------
  Onesheeld application that use 3 Shields : VoiceRecognition; Keypad; TextToSpeech. You must run those items in OneSheeld Android App,
  in order to use this application. With this you can allow up to 10 person to use some critical resources, doors, lock box etc, with
  name associate to a numeric password. In our case we use this program to control the cabinet doors of FabLab crew. In normal mode the
  person who want to use the resource, say is name in the VoiceRecognition section and then compone his password in the Keypad.
  All the operation are  articulated by a voice through TextToSpeech.
