Ported from tried and tested Ardupilot GPS UBLOX driver.

Features:

• Platform agnostic C++ (Arduino, PlatformIO, Linux, Windows, whatever...)
• Supports uBlox-6 to uBlox-M10 GPS
• Automatically configures baudrate
• Uses high speed ubx protocol
• Auto reconnect on communication loss
• Optionally save the config to the GPS module for faster restarts

Changes from ArduPilot:

• Moved all external dependencies into AP_GPS_UBLOX.h & .cpp
• Added pure virtual I_xxx methods as interface to the outside world
• Removed float (except LOGGING)

Requirements:

See example directory. Basically, implement the 7 pure virtual methods to get going.
