Task: Write a Java program to implement a simple graphics editor that can be used to draw a
Pythagoras. The editor has a pull-down menu on top of the screen, with 2 buttons: \"Pythagoras\"
and \"Quit\". 1) When the user selects \"Pythagoras\", he/she can draw a tree of Pythagoras on
the screen. 2) The editor terminates/quits execution if the user selects \"Quit\" from the pulldown
menu. 3) The editor has a horizontal and a vertical sliding bar that when slided, moves the tree
on the canvas accordingly.
