- Added the cohen sutherland line clipping algorithm in the object class
	& implemented the faceClip on faces of the cube, given the rectangular boundary
- TODO
	- Need to get the coordinates of the point after projection
	- Somehow get the orthographic matrix & multiply all the points in the faces,
		to get their new coordinates
	- HOW DO WE GET THE BOUNDARY OF THE RECTANGLE?
		- Assume a new cube & project it into projection plane & then it'll be a rectangle only
			& hence get the boundary this way
		- Or assume that its given to us?
	- Then clip the faces of the object 2 wrt this rectangular boundary, then plot the new faces obtained
