The above example fails due to a *shallow* root, a root which has a depth *smaller* than the first
root we encounter.

This example fails due to a *deep* root, a root which has a depth *larger* than the first
root we encounter.
.. image:: ../../images/subtree_fail_parent.svg
:align: center
:width: 800px
This example fails due to the fact that the parents of the subtree roots are not the same.
These conditions are checked using the functions defined in :code:`Subtree.h`.
This algorithm is used by :doc:`../API/JobTreeView` in the :code:`selectedSubtrees` method which is
required to implement non-trivial copy and paste.
