Updated 1st parameter to be "row" for transform, record & data events

I updated the README file and files in the doc directory.  I'm fairly sure I covered it all but I'm sure you know the documentation much better than I do.

I noticed the tests use 'record' as the parameter name.  I considered using that, but there is the event named 'record' so I stuck with the 'row' term for the 1st parameter.  Hope that sounds logical to you.
