## PuzzlePost
This project is a puzzle game in Java. The users are provided with a start and end point, and have to figure out their path
to get to the destination with constraints.

Makefile               This file provides for some
                       simple compilation/testing control.

    Makefile           A Makefile for compiling, style checking, testing, and
                       cleaning up files in this directory.

    Main.java          Entry point to program. This handles program options
                       and sets up the necessary objects to play one or more
                       games.

    Model.java         This class describes game state: the positions of
                       centers and barriers. It contains the logic for
                       adding and removing barriers, testing that constraints
                       are satisfied, and testing for a solution.

    Place.java         Encapsulates a position on the puzzle board.

    Controller.java    Contains the logic for controlling a game: responding
                       to commands by updating the model as apppropriate.

    CommandSource.java An interface that for classes that provide commands
                       to the Controller.

    GUISource.java     A CommandSource that fetches inputs from a user's
                       mouse actions.

    PuzzleSource.java  An interface to classes that can provide puzzles.

    TestSource.java    A CommandSource and PuzzleSource that fetches
                       commands and puzzles from the standard input.

    PuzzleGenerator.java
                       A kind of PuzzleSource that randomly generates
                       puzzles.

    View.java          Interface to classes that can display a Model.

    GUI.java           A View that represents the graphical display of the
                       game state and receives mouse actions from the user.

    BoardWidget.java   Used by GUI to represent the grid of squares and tiles.

    Utils.java         A collection of static utility methods.

    UnitTests.java     Main unit-test file.  This dispatches to other *Tests
                       classes for unit testing.

    ModelTests.java    Unit tests for class Model.

    PuzzleGeneratorTests.java
                       Unit tests for class PuzzleGenerator.


testing/                 Directory with integration test machinery.

    tester.py          A Python 3 script for testing your program.  It makes
                       use of the --testing option in your program to feed
                       in known moves.
    testing.py         A module that supports testing in general.
    *.in               Test scripts accepted by the tester.
    *.out              The outputs (logged by BoardLogger) expected for each
                       test.
