public class Interface
extends Frame
implements SolverGUI
Create a GUI interface for the Interval Arithmetic Solver. the Interface class is the "application" version of the Interval Arithmetic constraint solver in the ia_solver package.

This application creates a window with two main text areas and an assortment of control buttons and text fields. The Main text area is where the user enters constraints to be solved. The Result text area is where the answers are displayed.

Constructors

o Interface 
 public Interface(boolean isApplet)
This creates the GUI for the Interval Arithmetic Constraint Solver. The GUI has two major text areas. One for reading the constraints and another for printing the variable bindings. It also has a textfield for printing messages (status and error), and several buttons/choices/textfields for giving commands to operate on the constraints.
