``PathJoinSubstitution``
""""""""""""""""""""""""

``PathJoinSubstitution`` now supports concatenating strings or substitutions into a single path component.
For example:

.. code-block:: python

PathJoinSubstitution(['robot_description', 'urdf', [LaunchConfiguration('model'), '.xacro']])

If the ``model`` launch configuration was set to ``my_model``, this would result in a path equal to:

.. code-block:: python

'robot_description/urdf/my_model.xacro'
