Add support for data providers

[GoogleCodeExporter]

I would like to be able to add support for data providers, like the ones 
PHPUnit provides:

http://www.phpunit.de/manual/3.4/en/writing-tests-for-phpunit.html#writing-tests
-for-phpunit.data-providers

For now I'm using this helper for the job:

function DataProvider(func,args,bind){
    return function(){
       for (var i = args.length-1; i>=0; i--) func.apply(bind,args[i]);    
    };       
}

TestCase("A test",{
 "test data provider" : DataProvider(
       function(a,b){assertEquals(a,b)}
       , [ [1,2] , [2,2] , [3,3] ]
 });
);

but it doesn't run setUp and tearDown for each run. It also stops once one of 
the data provided fails, which misses the point.
