+
+    1) Main
+        Initializes static array of sudoku, points etc, intializes GUI as well
+    2) Solver
+        This Class has the algorithm to solve sudoku, It aslo refreshes GUI after every step
+        (Timer delay could be edited in this class)
+    3) guiController
+        Initializes GUI and provides various functions to retrieve/display/refresh the GUI
+    4) sudokuInitializer
+        This class allows input through Files
+        It also has a commented function which could take array values via console
+        (used only for debugging purpose)
