  Class holding mainly flags that are used across BMC
  For example when there's MIDI IN activity a MIDI IN flag is set,
  Leds will then read that flag and if an LED has a MIDI IN event it will pulse
  the led, every time BMC::update() happens the MIDI IN and OUT flags are cleared
  by this point the LEDs will have read that flag and they won't need to read it again.
  This object is decleared by the main BMC class, then passed as a reference to
  objects that may use it.
