//! A model encapsulating a satellite list.
//! Used for GUI presentation purposes.
//! 
//! It can show satellite names in their hint colors. This behavior can be
//! toggled with enableColoredNames(), e.g. to honor night mode.
//! 
//! @warning The model keeps a pointer to the satellite list, not a copy,
//! so every time that list is modified outside the model (i.e. satellites are
//! added or removed), you need to call beginSatellitesChange() and
//! endSatellitesChange().
//!
//! @todo Decide whether to use a table model with multiple columns (current),
//! or a list model dumping everything through data(). Both require enums - for
//! column numbers or data roles.
