NewHaven i2c displays do not function

Issue #26 wontfix
Former user created an issue

NewHaven display uses a Pic 16F690 as a controller. When the i2c flags are used with teh new Liquid Crystal library, the display does not appear to function. A typical part number is the one I am using NHD-0420D3Z-NSW-BBW. When I load a sample program that uses the wire library only, from here it works...

    While the LCD its self may be based on the HD44780 driver, it uses a proprietary interface to drive it (proprietary commands over the I2C, ISP or serial). This library does not support proprietary interface drivers other than those that drive the HD44780 directly.
