*To implement a custom model, you need to reimplement the following methods:
getIndex() and getParent() methods that allow one to navigate the model
getColumnCount() and getRowCount() to specify the top level geometry and the nested geometry at every item
getData() to return the data for an item
optionally, getHeaderData() to return row and column header data
optionally, getFlags() to indicate data options
