"""
The FlatNotebook is a full implementation of the wx.Notebook, and designed to be
a drop-in replacement for wx.Notebook. The API functions are similar so one can
expect the function to behave in the same way.

Some features:

  - The buttons are highlighted a la Firefox style
  - The scrolling is done for bulks of tabs (so, the scrolling is faster and better)
  - The buttons area is never overdrawn by tabs (unlike many other implementations I saw)
  - It is a generic control
  - Currently there are 5 differnt styles - VC8, VC 71, Standard, Fancy and Firefox 2;
  - Mouse middle click can be used to close tabs
  - A function to add right click menu for tabs (simple as SetRightClickMenu)
  - All styles has bottom style as well (they can be drawn in the bottom of screen)
  - An option to hide 'X' button or navigation buttons (separately)
  - Gradient coloring of the selected tabs and border
  - Support for drag 'n' drop of tabs, both in the same notebook or to another notebook
  - Possibility to have closing button on the active tab directly
  - Support for disabled tabs
  - Colours for active/inactive tabs, and captions
  - Background of tab area can be painted in gradient (VC8 style only)
  - Colourful tabs - a random gentle colour is generated for each new tab (very cool, VC8 style only)


And much more.
