Chris Taylor / Mbed 2 deprecated RayCastingEngine Featured

Ray casting engine implemented on the mBuino platform using the ST7735 LCD controller.

Dependencies:   LCD_ST7735 mbed

Ray casting engine written to test performance of the LCD_ST7735 library I wrote as a learning exercise on the mbed platform.
