 * @brief Implementation of the Protocol Widget API.
 * @author Mathias Winterhalter
 * @date 19.11.2020
 *
 * The RemminaPluginService provides an API for plugins to interact with Remmina. The
 * module called 'remmina' forwards this interface to make it accessible for Python
 * scripts.
 *
 * This is an example of a minimal protocol plugin:
 *
 * @code
 * import remmina
 *
 * class MyProtocol:
 *  def __init__(self):
 *      self.name = "MyProtocol"
 *      self.description = "Example protocol plugin to explain how Python plugins work."
 *      self.version = "0.1"
 *      self.icon_name = ""
 *      self.icon_name_ssh = ""
 *
 *  def init(self, handle):
 *      print("This is getting logged to the standard output of Remmina.")
 *      remmina.log_print("For debugging purposes it would be better to log the output to the %s window %s!" % ("debug", ":)"))
 *      self.init_your_stuff(handle)
 *
 *  def open_connection(self, handle):
 *      if not self.connect():
 *          remmina.log_print("Error! Can not connect...")
 *          return False
 *
 *      remmina.remmina_signal_connected(handle)
 *      remmina.log_print("Connection established!")
 *      return True
 *
 *
 *  def close_connection(self, handle):
 *      self.disconnect()
 *      return True
 *
 * plugin = MyProtocol()
 * remmina.register_plugin(plugin)
 * @endcode
 *
 *
 *
 * @see http://www.remmina.org/wp for more information.
