Minimal template for Pyside/PyQt QAbstractItemModel with typehints and notes. Based on documentation from https://doc.qt.io/qtforpython/PySide6/QtCore/QAbstractItemModel.html

Additional Notes

• The QAbstractItemModel should be thought of as an adapter class, although I typically do use it to fully encapsulate the data.
• An invalid model index (created by QtCore.QModelIndex()) object is used to refer to an invisible "root" node.
• Indexes to child objects should be created with the class' self.createIndex() (inherited implementation) method.
• I have typically found it useful to return a pointer to the full object in the ptr argument of self.createIndex(), then use the self.data() method in conjunction with the QModelIndex .row() and .column() methods to determine the actual data to return. Not always, but that usually works well.
