is_virtualis attribute is a bad idea to manage a virtual / ghost push button (used for testing purpose)

maybe we should have Button and GhostButton or VirtualButton

Pin have a board attribute so

function Led(board::AbstractBoard, pin::DigitalPin; lit_state=HIGH::PIN_VALUE)

should be replaced by

function Led(pin::DigitalPin; lit_state=HIGH::PIN_VALUE)

Board("") shouldn't always return a RaspberryPiBoard (should depend on which board it's running)

pin = Pin(GhostBoard(), Digital(), BCM(13))

function Board(s::AbstractString)
    s = lowercase(s)
    if s in ["", "rpi", "raspberry"]
        RaspberryPiBoard()
    elseif s in ["ghost"]
        GhostBoard()
    else
        error("'$s' is not an allowed board")
    end
end

function Board()
    Board("")
end

Should provide a register function

register!(Pingo.SUPPORTED_BOARDS, RaspberryPiBoard, ["rpi", "raspberry", "raspberrypi"])
