TANGO Device Server

1 - Init

• Description: This commands re-initialise a device keeping the same network connection.
  After an Init command executed on a device, it is not necessary for client to re-connect to the device.
  This command first calls the device delete_device() method and then execute its init_device() method.
  For C++ device server, all the memory allocated in the nit_device() method must be freed in the delete_device() method.
  The language device desctructor automatically calls the delete_device() method.
