A collection that contain links to {@link OIdentifiable}. Bag is similar to set but can contain several entering of the same object.
Could be tree based and embedded representation.
- Embedded stores its content directly to the document that owns it.
  It better fits for cases when only small amount of links are stored to the bag.
- Tree-based implementation stores its content in a separate data structure called {@link OSBTreeBonsai}.
  It fits great for cases when you have a huge amount of links.
The representation is automatically converted to tree-based implementation when top threshold is reached. And backward to embedded one when size is decreased to bottom threshold.
The thresholds could be configured by {@link OGlobalConfiguration#RID_BAG_EMBEDDED_TO_SBTREEBONSAI_THRESHOLD} and{@link OGlobalConfiguration#RID_BAG_SBTREEBONSAI_TO_EMBEDDED_THRESHOLD}.

This collection is used to efficiently manage relationships in graph model.

Does not implement {@link Collection} interface because some operations could not be efficiently implemented and that's whyshould be avoided.
