Title: Change colormaps for examples

Here's a bunch of colormap-related changes to the examples for Issue #875, intended to

1. discourage the use of the 'jet' colormap
2. encourage using diverging colormaps for bipolar data, sequential colormaps for unipolar data, cyclic colormaps for cyclic data
3. showcase a variety of different colormaps (hopefully I chose good-looking ones)

There are more that could be changed ([like this](http://docs.scipy.org/doc/scipy/reference/tutorial/interpolate.html#id1)), but I imagine even this set of changes needs discussion first.

(Also some typo and spelling fixes, which I probably should have done in a different branch, but I'm still learning how this git thing works)
