ARIA test harness

Hi Stefan, 

Please write complete the test harness (https://www.w3.org/wiki/ARIA_1.1_Testable_Statements) write up in the wiki for these tests:

aria-colcount in ARIA table
aria-colcount in ARIA grid

aria-colindex applied to a cell role

aria-colindex applied to a gridcell role

aria-colspan

aria-current


There are examples in the wiki for some of these. Some of these will require multiple test cases as aria-current will take on different values. In these cases you should write additional test for things like aria-current with new headers for each having a unique name. e.g.:

=== aria-current ===

would change to 

=== aria-current with value page ===
=== aria-current with value time ===

and so on. We will check in on your progress at the Thursday ARIA call. 

Best,
Rich
