/**
 * Defines the custom layout template options used by the [Print widget](https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Print.html) and
 * [Print component](https://developers.arcgis.com/javascript/latest/references/map-components/arcgis-print/) to generate the print page. While custom templates can be published from ArcGIS Pro to a portal,
 * custom layout templates are defined in a portal, where they can be added, removed, or edited as necessary
 * without having to republish the print service. There are a limited number of options available for customization.
 *
 * The main benefit of this class is that it allows developers to give a name to a preferred `format` and `layout`
 * and if there should be a `Legend` present or not, in a reusable way. This is what the UI looks like in a portal:
