Use this function to implement how the EyeTracker should obtain
		a frame. A frame is supposed to be a two-dimensional image, usually
		an image from a webcam or a video that was converted to greyscale.
		Note that a frame should be a numpy.ndarray with shape=(w,h), and
		dtype='uint8'. In addition to the frame, a success Boolean should
		be returned by this function. It tells the functions that call
		_get_frame whether a new frame was available. (See below what the
		returned values should be exactly.)
		
		IMPORTANT: This function should not have any keyword arguments.
		Any settings should be handled through properties of self.
		
		Returns
		
		success, frame	-	success is a Boolean that indicates whether
						a frame could be obtained.
						frame is a numpy.ndarray with unsigned,
						8-bit integers that reflect the greyscale
						values of the image. If no frame could be
						obtained, None will be returned.
