setting 'grid' to false still shows grid.
easy fix

plawt's 'subtitledict' becomes the fontdict for matplotlib's [axes.set_title](https://matplotlib.org/api/_as_gen/matplotlib.axes.Axes.set_title.html).

Only the 'verticalalignment' field of fontdict has the intended effect, and with inconsistently as well (you have to put 'center' when you mean 'bottom').
I think this is a matplotlib issue and not a plawt issue.

I can currently make animations using plawt and imageio like this (for example):

animation = {
		'ylabel': 'z/H', 'xlabel': 'r/H',
		'ylim': (-2, 10), 'xlim': (-6, 6),
		'figsize': (6/1.3, 6.5/1.3),
		'title': 'Likely how W4 expanded',
		'show': False,
		'keepOpen': True,
		'legend': {'loc':4}
	}
	y = np.arange(0.01, 2.05, 0.05)
	with imageio.get_writer('blast.gif', mode='I', fps=24) as writer:
		for i, t in enumerate(tqdm(y)):
			animation[0] = {'x': np.concatenate((r(z, y[i]), -r(z, y[i]))), 'y': np.concatenate((z,z)),
				'line':'k-', 'label':'$y=$'+str(y[i])}
			plt = plawt.plot(animation)
			fig = plt.gcf()
			fig.canvas.draw()
			data = fig.canvas.tostring_rgb()
			row, col = fig.canvas.get_width_height()
			image = np.fromstring(data, dtype=np.uint8).reshape(col, row, 3)
			writer.append_data(image)
			plt.close()

But I want to abstract some of the details away.
The method above is essentialy generating bitmap as frames and putting them together, but matplotlib has its own api for animating using functions which might be more efficient. I'll need to look into that and maybe support both ways of animating. (http://matplotlib.org/api/animation_api.html#animation)

I want to be able to specify sizes of figures in pixels using plawt..
see answer here:
https://stackoverflow.com/questions/13714454/specifying-and-saving-a-figure-with-exact-size-in-pixels

the interface could be something like

plawt.plot([{
    0: {'x': x, 'y': y},
    'xlabel': 'some label',
    'filename': 'plot.png'
}, {
    0: {'x': x2, 'y': y2},
    'xlabel': 'some other label'
}])

That is, pass mutliple 'plot' dictionaries and inherit global properties like title or filename from the first plot dictionary as a convention

right now things internally are done by importing pyplot and then calling things like plt.plot(), plt.xlabel(), etc... this is not great because i have to do weird if/else branches if for example only an x axis is provided and the call signature to plt.plot() is different. (also i got bashed on reddit for doing it this way and i kinda agree)

matplotlib has an api where you can do things like axis.xlabel = 'blah blah' and i think this might be a cleaner and more extensible way to have plawt work. But I don't really know this api and I need to look into it
