Partial implementation of BlueGiga's BGAPI for use with the BLE112/3 modules over UART.

Hi there! I recently started using BLE112 modules with the mbed LPC1768 MCU, and I realized there was no implementation of BlueGiga's BGAPI available for mbed. This library implements only a few commands, but if you're looking to get started, this is a good place to look.

This was developed against BGAPI v1.3.2. I make no guarantees as to how well it will work with newer revisions of the software.
