Makes a nifty corner plot.

Uses :func:`triangle.corner`.

:param params: (optional)
    Names of columns (from :attr:`StarModel.samples`)
    to plot.  If ``None``, then it will plot samples
    of the parameters used in the MCMC fit-- that is,
    mass, age, [Fe/H], and optionally distance and A_V.

:param query: (optional)
    Optional query on samples.

:param extent: (optional)
    Will be appropriately passed to :func:`triangle.corner`.

:param **kwargs:
    Additional keyword arguments passed to :func:`triangle.corner`.

:return:
    Figure oject containing corner plot.
