/**
 * User entry field, allowing selection of a user from a modal dialog
 *
 * Use this by extending it (I'm using -at- instead of the actual at-sign)
 * -at-include('any:lib_fof40/Common/user_select', $params)
 *
 * This is the generic variant used in Joomla 4 (when NOT using the FEF renderer)
 *
 * $params is an array defining the following keys (they are expanded into local scope vars automatically):
 *
 * @var string                  $field       The user field's name, e.g. "user_id"
 * @var \FOF40\Model\DataModel  $item        The item we're editing. The user ID is stored in $item->{$field}
 * @var string                  $id          The id of the field, default is $field
 * @var bool                    $readonly    Is this a read only field? Default: false
 * @var string                  $placeholder Placeholder text, also used as the button's tooltip
 * @var bool                    $required    Is a value required for this field? Default: false
 * @var string                  $width       Width of the modal box (default: 800)
 * @var string                  $height      Height of the modal box (default: 500)
 *
 * Variables made automatically available to us by FOF:
 *
 * @var \FOF40\View\DataView\DataViewInterface $this
