Title: Add cdfplot

WIP for now. Closes #2669

I'm using statsmodels' KDE implementation right now; it has a `cdf` method, but scipy's gaussian_kde doesn't. I need to check the math, but I think something like doing a cumsum on the density and normalizing by the sum should be the same.

I'm also going to add kwargs for things like the inverse cdf.
