Position Data working

Tweaked encoder read patterns and gyroscopes to get accurate position reads

PositionAdjust() was not correctly interpreting encoderR == encoderL. The else statement was returning strange values, the system seems to work fine with their removal, so I left it commented.

Fixed the reset function to work at 115200 baud rate

renamed x and y to xcoord and ycoord for easier searches

'quit' now closes the serial connection.
