   * name with a hyphen `-`.  This means that set names cannot contain a hyphen.
   *
   * @param  name the namespace of the icon set
   * @param  path the web-accessible path to the icon set (for instance, a CDN)
   * @param  resolveIconName an optional function to combine the path and an icon name into a final path.  The function will be passed the namespaced icon name (for example, "rh-api" where rh is the namespace and api is the individual icon's name)
   * @returns  an object with the status of the icon set installation, such as `{ result: true, text: 'icon set installed' }` or `{ result: false, text: 'icon set is already installed' }`
