 This example demonstrates a very simple use of the SevSeg library with a 4
 digit display. It displays a counter that counts up, showing deci-seconds.

testWholeDisplay.ino
-test each segment in the display
-a simple example using Dean Reading's SevSeg library to light up all 4 digits plus the 4 decimal points on a 4 digit display
-the purpose of this example is to ensure you have the wires all hooked up right for every segment and digit, and to troubleshoot the display and wiring
 to ensure *every* segment and period lights up
