     Each World has an - invisible - "Hand" resembling the mouse cursor

     The basic idea of Morphic is to continuously run display cycles and
     to incrementally update the screen by only redrawing those  World
     regions    which have been "dirtied" since the last redraw. Before

+-thread.js
+    -Modification to startProcess in order for detection of debugging mode toggle
+-gui.js
+    -Implementation of the pointer arrow as well as stepping interface for user
+    control of iteration through block
+- Add a stop block which simply acts as a block where we should stop the debugging execution.
+- Evaluate code for play/pause buttons and determine how they carry out their functionality 
+-   Using this knowledge generate a stepper button and insert into gui which would then create 
+-   
+there is a **allHatBlocksFor** method within objects which determines which kind of hat blocks to add to an array
