//***********************************************************************************************
//    ResListManager class
//***********************************************************************************************

//! The ResListManager is a \a singleton class which manages presets of camera
//! resolutions.
/*!
  This class allows a lightweight management of the resolution presets used in
  camera settings.
  Specific tasks include resolution fetching and the add/remove functions.
  Adding or removing
  presets causes the listChanged() signal to be emitted.

  \note There actually are \a two distinct instances of this class, one managing
  standard cameras
        and the other for cleanup cameras. Presets are stored in two distinct
  files as well.
