Public Methods
LinkToChild CreateView (FakeFlatlandSession & parent_session)Links this session to |parent_session| and returns the LinkToChild, which should be used with
the parent session. If the return value drops out of scope, tests should call
ClearLinkToParent() on this session.

std::unique_ptr<UberStruct> CreateUberStructWithCurrentTopology (TransformHandle local_root)Allocates a new UberStruct with a local_topology rooted at |local_root|. If this session has
a LinkToParent, the child_transform_handle of that LinkToParent will be used instead.

void PushUberStruct (std::unique_ptr<UberStruct> uber_struct)Pushes |uber_struct| to the UberStructSystem and updates the system so that it represents
this session in the InstanceMap.
