BGLib for Squirrel

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)

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:



	// -----------------------------------------------------------------------------
	// WifiTimezone class
	//
	// Requests the imp to scan for wifi networks, sends that data to Google Maps to
	// geolocate the imp, sends that data to Google Maps to collect timezone data
	//
	class WifiTimezone {


	// Pin 2 is the red LED
	ACTIVITY <- hardware.pin2;
	ACTIVITY.configure(DIGITAL_OUT);
	ACTIVITY.write(1);

	// Pin 8 is the orange LED
	LINK <- hardware.pin8;
	LINK.configure(DIGITAL_OUT);
	LINK.write(1);

	class NeoPixels {

	// when instantiated, the neopixel class will fill this array with blobs to
	// represent the waveforms to send the numbers 0 to 255. This allows the blobs to be
	// copied in directly, instead of being built for each pixel - which makes the class faster.
	bits = null;

	// Like bits, this blob holds the waveform to send the color [0,0,0], to clear pixels faster
	clearblob = null;


	server.log("Agent started, URL is " + http.agenturl());

	// This is a really simple, reusable wrapper for any internal object to turn it into a class.
	// For memory and performance reasons, the built-in classes are not real classes so can't
	// be extended in the normal way.
	class impWrapper {
	_wrapped = null;

	constructor(wrapped) {
	_wrapped = wrapped;
	}
