* This class provides the ability for an artifact to link to an artifact on another branch. It is not a full featured
* link and is also omni-directional, so care must be taken when using this.<br>
* The information for this link is stored as attributes on the sideA artifact. User needs to be aware that the relation
* type, branch and artifact may not exist when the link is accessed, so care must be taken when using this.<br>
* <br>
* Link uses the Cross Branch Link attribute which must be added as a valid attribute on the SIDE_A artifact type. <br>
* <br>
* TODO Remove this class and replace with framework cross branch links when available.
