/*!

|
* \brief Class that each instance type's version list derives from.
|
|
* Version lists are the lists that keep track of the available game versions
|
|
* for that instance. This list will not be loaded on startup. It will be loaded
|
|
* when the list's load function is called. Before using the version list, you
|
|
* should check to see if it has been loaded yet and if not, load the list.
|
|
*
|
|
* Note that this class also inherits from QAbstractListModel. Methods from that
|
|
* class determine how this version list shows up in a list view. Said methods
|
|
* all have a default implementation, but they can be overridden by plugins to
|
|
* change the behavior of the list.
