    Background:
    I have had many people ask for an LED type indicator for their project. During development, I often get asked to have this Boolean (ie 2 state) indicator display one of (more than 2) colours.
    Whilst that in itself is not difficult, more often than not I am then asked to make the Boolean LED flash as well to highlight certain states.
    For example a single LED will often need to indicate the following states:
    OFF (green, red or grey)
    ON (Green, red or grey)
    Flashing (green, red, any other colour)
    I have had so much demand for this functionality, that I decided to develop this XControl and share it with the LabVIEW Community.
    Many thanks must go to Aristos Queue and his inspiring "Scrolling LED XControl" example.
    Description:
    This XControl is a typical Boolean LED indicator that can also be configured to flash between two user defined colours. The flashing interval can also be modified.
    When not flashing, the XControl behaves as a normal Boolean LED.
    This XControl is an indicator only is is not intended to be used as a control.
    Dependancies:
    There are no OpenG dependencies for this XCtonrol
    Known Issues:
    If you save this code for version 8.0/8.2, you may encounter issues trying to assign multiple properties in one property node.
    This is a bug in LabVIEW 8.0/8.2
    Change Log:
    1.0.0 Initial release
