* Multi Bean Loader Helper

* This code was originally part of the facade, however it has

* this to make them available to developers not using the facade class.
*
* This helper class offers limited support for one-to-one
* relations by providing a service to load a set of beans
* with different types and a common ID.

/**
* Loads multiple types of beans with the same ID.
* This might look like a strange method, however it can be useful
* for loading a one-to-one relation. In a typical 1-1 relation,
* you have two records sharing the same primary key.
* RedBeanPHP has only limited support for 1-1 relations.
* In general it is recommended to use 1-N for this.
*
* Usage:
*
* <code>
* list( $author, $bio ) = R::loadMulti( 'author, bio', $id );
* </code>
*
* @param OODB $oodb OODB object
* @param string|array $types the set of types to load at once
* @param mixed $id the common ID
*
* @return OODBBean[]
