Features and Screenshots to README.md

[buhtz]

Could you please give some screenshots and describe the features. What is the advantage in comparision to Tkinter's own widgets?

@gpip Would you be able to exhaustively describe the features that this widget provides?

hey, thanks for the mention but it's been a long time since I used it myself. I'd guess you know more about it than I do, but it's an extra widget so I don't think I understand the original question (what's the advantage in relation to other widgets). Unless there's a spreadsheet-like widget for Tk, tktable would save you a lot of time to get done an application that has that sort of requirement.

tktable describes itself as a (complex) blend of Tk entry, listbox, and text widgets.
