/**
 * This widget displays the speed in either MPH or KPH .
 * It also visually display different colors around the pit road speed limit.
 * Yellow as you approach the limit, Green at the limit, Red above the limit.
 * In addition, there is a series of lights that indicate where you are between these states.
 * <p
 * States:
 * <p>
 * <ul>
 * <li>APPROACHINGLIMIT - you are approaching the pit road speed limit</li>
 * <li>LIMIT            - You are near the pit road speed limit</li>
 * <li>OVERLIMIT        - You are over the pit road speed limit</li>
 * <li>WAYOVERLIMIT     - You are way over the pit road speed limit</li>
 * <li>SHIFT            - indicates it is time to shift to the next gear</li>
 * <li>CRITICAL         - indicates it has red-lined</li>
 * </ul>
 * Example:
 * <p><b>
 * <sra-analog-gauge-spek-speedometer data-sra-args-show-digital-value="false"></sra-analog-gauge-speedmeter>

 * @ngdoc directive
 * @name sra-analog-gauge-spek-speedometer
 * @param {boolean} data-sra-args-show-digital-value Set to true or false for displaying the digital value. Defaults to true. Can be overridden from the URL with "SHOWDIGITALVALUE=false".
 * @param {double}  data-sra-args-round-to The value to round the digital display to. Defaults to 1. Can be overridden from the URL with "TACHROUNDTO=10".
 * @param {integer} data-sra-args-interval The interval, in milliseconds, that this widget will update from the server. Default is 16.
