I think it makes sense to create our own directory, power_cases, to mirror all
of the other .+_cases directories

Those subdirectories look like they mostly contain html pages. Since this
contains no html, I do not think it makes sense at this moment to do that.

[rnephew (Reviews Here), 2016/05/16 20:05:57]

Done.

It looks like
https://code.google.com/p/chromium/codesearch#chromium/src/tools/perf/page_se...
contains only .py files, but still has its own subdirectory. 

If we know that we're going to have more power test cases in the future, why
create more work for ourselves by not placing it there now? Isn't the first
person to write a second benchmark going to have to go back and rewire the
imports to reflect the new directory?

Done.

Is the lack of autoplay going to be a problem on Android devices? (I guess we
don't have any Android devices w/ BattOrs right now, so it's definitely not a
blocker)
