Hexdump

This function will dump a blob or string as a hexdump to a serial port.

The input looks like this:

hexdump("RECV", "Hello world\n", "uart57");

The output (with a more complex input!) will look like this:

This implements the BGLib library for Bluegiga's BLE112 Bluetooth Smart module.

It assumes you have connected from the Imp to the BLE112:

UART (uart1289 is recommended as flow control is important)
Wake pin (optional depending on BLE112 configuration)
Reset pin (optional but really helpful as software reset is not always reliable)
