bobot library

Example usage:
	bobot=require("bobot")
	bobot.init()

init() can receive a list of connectors to use. Supported values are "usb", "serial" and "chotox".
For example, to only use de dummy chotox driver, use init({"chotox"})
If no parameter is provided, behaves like init({"usb","serial"}).
