Find better way to fix image cropping in docs.

[jberlanga]

Docs use Matplotlib's .. plot:: directive, which incorrectly crops off edges of images produced by plotting code (see Matplotlib issue here, resulting in behavior like that below:

Need to find a better way to fix this other than sticking the following block of code before every plt.show() instance, as this obscures the astroplan code that the docs are meant to illustrate:

# Note that you don't need this code block to produce the plot.
# It reduces the plot size for the documentation.
ax = plt.gca()
box = ax.get_position()
ax.set_position([box.x0, box.y0, box.width * 0.75, box.height * 0.75])

Try calling plt.tight_layout() before the final plt.show() call in this plotting examples.

@cdeil -- Unfortunately, plt.tight_layout() did not work. See the very last example plot here, which is made by the last block of code in summer_triangle.rst.

@cdeil -- Are you ok with moving this to 0.2?

[cdeil]

Sure ... I just moved it.
