Brush up the taskmenuextension example

When porting the code to Python, some issues showed up.

- Rewrite cellRect() to take the position (reason being
  that porting the existing code to Python creates
  problems with implicit conversion to float in the division).
- Use plain assignment by operator[] to replace the characters
  in the string
- Avoid repeating return types.
- Streamline code.
- Initialize myState member variable.
- Indicate C++ in the tool tip
