/**
 *
 *  A reference to an entity in a group.
 *
 *  The entity group id can be null, which means the entity is in the same group as the user currently logged in to the
 *  SDK.
 *
 *  When providing input to any SDK method you can use references with the group of the logged user or null
 *  interchangeably.
 *
 *  However, some SDK methods that return [EntityReferenceInGroup] consistently fill the [groupId] of the logged user
 *  while others consistently leave it null.
 *  The general rule is that the methods from `inGroup` apis always fill all [groupId] values, even when the group
 *  matches the current user's group. Methods that always act on the logged user's group instead always leave null
 *  [groupId] when it would match the logged user's group.
 *
 *  Note that `equals` methods can't take in consideration the group of the current user, therefore
 *  `EntityReferenceInGroup(x, userGroup) != EntityReferenceInGroup(x, null)`, even though the SDK for a user in
 *  userGroup treats them the same.
 *
 *  @param entityId the id of the entity
 *  @param groupId the id of the entity's group. If null it should be interpreted as the same group of the logged user.
