Data table heuristics: consider assuming data table for 'zebra-striped' rows

* NOTES
We should consider adding a data table heuristic if every other row is an alternating color. 'zebra-striped' rows are a common design pattern. See screen shot that was not triggered as a data table before the ARIA roles were added.

Why a variable-size vector here instead of a fixed array?

If you have to do type casting, you should do a C++ cast, not C.

I'm not sure "cache" is the right name for this data structure. I'd just call it rowColors.

Code seems OK, I’ll say r=me
