	The Code Below is used to develop a Checker Board Pattern.

	1. Start with Identifying the First Square
	2. Put in the coordinates for the First Square
	3. Create a for-loop to to create squares at the same time
	4. Introduce a variable to help keep track of the color. Using an IF Statement.
	5. Introduce an outer for-loop to cater for the y - axis.

// We will be doing animation in OpenGL
// key concepts are:
// 1. the idle function - idle() will post a replaint and this will lead to activation of the display() function
// 2. Also we will be doing double buffering like this: glutInitDisplayMode(GLUT_DOUBLE);
// In addition we will be introducing other functions such as glPushMatrix, glPopMatrix and glSwapBuffers
