##  Base class for output device plugins.
#
#   This class provides the base for any output device plugin that should be
#   registered with the OutputDeviceManager. Each OutputDevicePlugin should
#   implement device detection and add/remove devices as needed.
#
#   For example, the Removable Device plugin searches for removable devices
#   that have been plugged in and creates new OutputDevice objects for each.
#   Additionally, whenever a removable device has been removed, it will remove
#   the OutputDevice object from the OutputDeviceManager.
