     /**
     * Tools, together with {@link OO.ui.ToolGroup toolgroups}, constitute {@link OO.ui.Toolbar toolbars}.
     * Each tool is configured with a static name, title, and icon and is customized with the command to carry
     * out when the tool is selected. Tools must also be registered with a {@link OO.ui.ToolFactory tool factory},
     * which creates the tools on demand.
     *
     * Every Tool subclass must implement two methods:
     *
     * - {@link #onUpdateState}
     * - {@link #onSelect}
     *
     * Tools are added to toolgroups ({@link OO.ui.ListToolGroup ListToolGroup},
     * {@link OO.ui.BarToolGroup BarToolGroup}, or {@link OO.ui.MenuToolGroup MenuToolGroup}), which determine how
     * the tool is displayed in the toolbar. See {@link OO.ui.Toolbar toolbars} for an example.
     *
     * For more information, please see the [OOUI documentation on MediaWiki][1].
     * [1]: https://www.mediawiki.org/wiki/OOUI/Toolbars

     *  the {@link #static-title static title} property is used.
     *
     *  The title is used in different ways depending on the type of toolgroup that contains the tool. The
     *  title is used as a tooltip if the tool is part of a {@link OO.ui.BarToolGroup bar} toolgroup, or as the label text if the tool is
     *  part of a {@link OO.ui.ListToolGroup list} or {@link OO.ui.MenuToolGroup menu} toolgroup.
     *
     *  For bar toolgroups, a description of the accelerator key is appended to the title if an accelerator key
     *  is associated with an action by the same name as the tool and accelerator functionality has been added to the application.
     *  To add accelerator key functionality, you must subclass OO.ui.Toolbar and override the {@link OO.ui.Toolbar#getToolAccelerator getToolAccelerator} method.
