First Draft of Main Board

1. Added most of the main board parts in the schematic.
2. Board layout needs work. the backlight timing circuit needs to be
tested.
3. Part sizes need to be double checked.
4. Need to add molex connectors for Input, I2C Bus, and Power Bus
5. Double check decoupling capacitors
6. Ensure Soldering is on the bottom side
7. Change LCD Part pin locations according to actual device. At the
moment, I have just used a pre-made part that has 16 pins @ 2.54mm pitch
spacing but the 16 pins need to be at the right location.
8. Keep in mind that the PCB will be mounted onto a face plate so needs
consideration on the side that the components are mounted on since the
height of each component matters.
9. Use sockets for ICs for the prototype
