* Initializes a bulk edit object
*
* This object have an ID that identifies the group of selected items that are to be affected by the changes.
*
* When itialized it adds a postmeta to the posts of these groups so they can be easily fetched as a group in all operations.
*
* The object can be initialized in three different ways:
* 1. passing an array of Items IDs, using the items_ids params
* 2. passing a query array, that will be passed to the fetch method of items repository to create the group (in this case you also need to inform the collection id)
* 3. passing an group ID, generated by this class in a previous initialization using one of the methods above.
*
* When initializing using methods 1 or 2, controllers should then call the get_id() method and store it if they want to perform future requests that wil affect this same group of items
*
* Note: if the ID paramater is passed, other paramaters will be ignored.
*
* @param array $params {
*
* Initialization paramaters
*
* @type int $collection_id The items collection ID. Required if initializing using a query search
* @type array $query The query paramaters used to fetch items that will be part of this bulk edit group
* @type array $items_ids an array containing the IDs of items that will be part of this bulk edit group
* @type string $id The ID of the Bulk edit group.
