 public Bottomcontrolstuff(Curveline bzl)
This constructor adds buttons as required per the context of the class. Different types of curves required different buttons. The buttonss are created here according to a series of if () statements.

Methods

o actionPerformed 
 public void actionPerformed(ActionEvent ae)
This function performs actions for each button push. A series of if statements analyses which button was pushed, and determines an appropriate action. There are nested if() decisions made, so that a few buttons can perform different actions, based upon the context and the curve type drawn. Handles are used to get back to key parameter values and to get back to other objects to enable the repaint() command!
