Add a centered title to the figure.

kwargs are :class:`matplotlib.text.Text` properties.  Using figure
coordinates, the defaults are:

  - *x* = 0.5
      the x location of text in figure coords

  - *y* = 0.98
      the y location of the text in figure coords

  - *horizontalalignment* = 'center'
      the horizontal alignment of the text

  - *verticalalignment* = 'top'
      the vertical alignment of the text

A :class:`matplotlib.text.Text` instance is returned.

Example::

  fig.subtitle('this is the figure title', fontsize=12)
