Adds a new item to the layout

@param string      $id        The layout item id
@param string      $parentId  The id or alias of parent item. Set null to add the root item
@param mixed       $blockType The block type associated with the layout item
@param array       $options   The layout item options
@param string|null $siblingId The id or alias of an item which should be nearest neighbor
@param bool        $prepend   Determines whether the moving item should be located before or after
the specified sibling item

@throws Exception\InvalidArgumentException if the id or parent id are empty or invalid
@throws Exception\ItemAlreadyExistsException if the layout item with the same id already exists
@throws Exception\ItemNotFoundException if the parent layout item does not exist
@throws Exception\LogicException if the layout item cannot be added by other reasons
