"""Add a new panel to the current panel bay
Parameters
----------
y1 : float
Position of the first panel edge along `y`.
y2 : float
Position of the second panel edge along `y`.
stack : list, optional
Panel stacking sequence. If not given the stacking sequence of the
bay will be used.
plyts : list, optional
Thicknesses for each panel ply. If not supplied the bay ``plyts``
attribute will be used.
plyt : float, optional
Unique thickness to be used for all panel plies. If not supplied
the bay ``plyt`` attribute will be used.
laminaprops : list, optional
Lamina properties for each panel ply.
laminaprop : list, optional
Unique lamina properties for all panel plies.
model : str, optional
Not recommended to pass this parameter, but the user can use a
different model for each panel. It is recommended to defined
``model`` for the bay object.
mu : float, optional
Panel material density. If not given the bay density will be used.
Notes
-----
Additional parameters can be passed using the ``kwargs``.
