So #293 seems to be working well. We should consider rolling this out for all the methods we have implemented. As a general preference, do we want to use a...

Cool. Will give that a stab. How do I get the derivative of df, where f is the function of the total field intensity though? The rest of the tilt...

Just to confirm then, `derivx` and `derivz` will get the `df/dx` and `df/dz`? That would mean that tilt would be implemented by something like: ~~`def tilt(x, y, data, shape):`~~ ~~`horiz_deriv...

Looks like Mayavi might finally be moving over to Python3 as well: http://docs.enthought.com/mayavi/mayavi/auto/changes.html?highlight=python3 which I think was out major block, correct?

Been taking a look at this, and it looks like more recent versions of matplotlib do not allow for custom hatch patterns. For now at least, the workaround here in...

There are a number of cases that should probably be handled: 1. Only tops are given - bases are inferred to be the next top. 2. Only bases are given...

https://gist.github.com/mtb-za/3f94ffc426e804e7b2c778c2f0c6f051 has a couple of approaches, one using `np.genfromtxt` and one using `csv.DictReader`. Not sure if one appeals to you more than another one. If we want to get input...
