BUG: Example checker has problems suppressing type information

[bmwoodruff]

The example-checker.ipynb has problems supressing type information. Instead of displaying 0.0, it will display np.float64(0.0). Part of the issue was to format arrays properly, but in doing so we now get all kinds of extra type information being displayed.

It would be nice if the example checker could automate supressing type information, while still maintaining a nice clean format for arrays. One option might be array2string, which I tried with little success when first creating the checker. It needs more work. For now, you have to remove the extra type information, which is a bit better than trying to properly format output and smashing the space bar.

• I'll mark this complete when I don't see type information showing up in examples for a week.

The new example checker found in the tools/review/ folder has tried to address this a bit. It correctly handles multiline output and arrays (even if on one line), but there could be some instances where a single value returned ends up showing repr() instead of print() value. With time, it should work the way we want it.

I saw some today, so this still has more work.
