Feature Calculation in Pattern Class

    int mallocmemory();
	Return Value
	0.................Normal completion
	MEMORY_SHORTAGE...Insufficient memory
	void mcalcall(OCRBuffer* pocrbuffer,OCRRect* prect,int background);
	Input
	OCRBuffer	aocrbuffer;
				top......Address of the image buffer
				width ...Width of the image buffer (byte boundary, in pixels)
				height...Height of the image buffer (in pixels)
	OCRRect		arect;
				x1...Top left X-coordinate of the pattern
				y1...Top left Y-coordinate of the pattern
				x2...Bottom right X-coordinate of the pattern
				y2...Bottom right Y-coordinate of the pattern
	int			background;
				0...Background is bit 0
				1...Background is bit 1
