Copy the default corner_kwargs
Currently, in _make_corner_plot
in plot.py
te default_kwargs
directly points to conf.corner_kwargs
. This means that conf.corner_kwargs
itself gets updated and if this function is called again within the same session any previous values (including previous figure objects) stay within the kwargs. This PR instead makes default_kwargs
and copy of conf.corner_kwargs
so the previous values do not get kept.
