Qt 4.8 Model/View Tutorial - Part 1

The following code was adapted from the Qt Model/View Tutorial - 2.1 A Read Only Table.

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

'''
    PyQt4 conversion of Qt Model-View Tutorial
    
     Creating a read-only Table View using QTableView
     
    NOTES:
    =====
    For some reason, calling a main() function to start the
    application as in earlier examples produces a runtime error 
    when the application is closed:
        QObject::startTimer: QTimer can only be used with threads 
          started with QThread

    Start the application directly and no error occurs.
