-Fixed a bug with the view controller where the view doesn't have proper width and height (when the ipad is on its side), thus causing the view space transformations to have the wrong information
-Created the visual components for the buttons which will change the snake's direction
-Fixed a problem with scale transformations being set to 0, causing touch input to not be calculated properly
-Small Change
-Created a joystick script that will allow the snake to turn through player input instead of randomly
-Removed the touch processing component of the snake script
-Added the drawable component property to snake chunk objects
-Added the GLKit framework to be linked with the transformationTests target
-Created a test class for testing rotation transformations
-Created a test for the situation where a rotation transformation has its x,y,z components all set to zero
-Created an assert in the rotation tranformation objects to check for x,y,z components all being set to zero
-Created a test class for testing scale transformations
-Created some code for testing the scenario where at least one of the components of a scale transformation is set to zero, causing the resulting inverse transformation to be undefined
-Created an assert for checking when an inverse transformation matrix is requested from a scale transformation object that has one of its parameters set to zero
-Added a test scenario to rotation transformations for checking whether the object returns transformation matrices under normal circumstances
-Small Change
-Made a mistake with the assertion in the rotation transformation code. Now it's fixed
-Created a test class for testing uniform scale transformations
-Created testing scenario to check whether uniform scale transformations would throw an exception when their scale property is set to zero, and would not throw an exception when its properties are set to a normal circumstance
-Created an assert in the uniform scale transformation objects to check for when the scale property is set to zero and an inverse transformation is requested
