We added DataProvider.map()
We added method DataProvider.map(), which can be used to map row's values to any other values. It's useful for separating content of the data provider from the form (if the form is non-trivial) and for adapting similar DataProviders to be used in more tests.
More features will be coming, in current beta there are: DataProvider.filter(), DataProvider.reindex(), DataProvider.reindexTo() and some others.
