/**
 * This class is is responsible for adding objects to another object's has_many
 * and many_many relation, as defined by the {@link RelationList} passed to the
 * {@link GridField} constructor.
 *
 * Objects can be searched through an input field (partially matching one or
 * more fields).
 *
 * Selecting from the results will add the object to the relation.
 *
 * Often used alongside {@link GridFieldDeleteAction} for detaching existing
 * records from a relationship.
 *
 * For easier setup, have a look at a sample configuration in
 * {@link GridFieldConfig_RelationEditor}.
