Special Properties
1. BackColor : Set to indicate the background color (default = black)
2. SegmentColor : Set to indicate the color of the segments on the LED digit
(default = yellow)
3. MinValue : Minimum allowable value for display (default = 0)
4. MaxValue : Maximum allowable value for display (default = 9)
5. Value : Integer value representing the display value (default = 0)
6. BlankWhenZero : Boolean value indicating whether to display a zero or
blank when the value is zero (default = false, i.e.
display zero)
7. LEDDisplayType : Enumerated type which causes the digit to display a colon
a decimal point or the value property. (useful for building
panels, default = digit)
Special Methods
1. Increment : Increases the digit value by 1, if the value exceeds
MaxValue then the digit rolls back to MinValue.

MinValue then the digit rolls forward to MaxValue.
Special Events
1. OnRollForward : Event fired when Increment causes a rollover.
2. OnRollBackward : Event fired when Decrement causes a rollover.
