-/**
- * Telemetry.
- *
- * To add metrics for a tool:
- *
- * 1. Create boolean, flag and exponential entries in
- *    toolkit/components/telemetry/Histograms.json. Each type is optional but it
- *    is best if all three can be included.
- *
- * 2. Add your chart entries to browser/devtools/shared/telemetry.js
- *    (Telemetry.prototype._histograms):
- *    mytoolname: {
- *      histogram: "DEVTOOLS_MYTOOLNAME_OPENED_BOOLEAN",
- *      userHistogram: "DEVTOOLS_MYTOOLNAME_OPENED_PER_USER_FLAG",
- *      timerHistogram: "DEVTOOLS_MYTOOLNAME_TIME_ACTIVE_SECONDS"
- *    },
- *
- * 3. Include this module at the top of your tool. Use:
- *      let Telemetry = require("devtools/shared/telemetry")
- *
- * 4. Create a telemetry instance in your tool's constructor:
- *      this._telemetry = new Telemetry();
- *
- * 5. When your tool is opened call:
- *      this._telemetry.toolOpened("mytoolname");
- *
- * 6. When your tool is closed call:
- *      this._telemetry.toolClosed("mytoolname");
- *
- * Note:
- * You can view telemetry stats for your local Firefox instance via
- * about:telemetry.
- *
- * You can view telemetry stats for large groups of Firefox users at
- * metrics.mozilla.com.
