Memory issues using datasets

Great tool! I have been testing it with our suite of DBFit tests. Everything works fine when I only run a small set of tests, but when the trace data gets large I am seeing memory issues. I created a console app to test SQLCover in the debugger and see where the issue was. I am getting out of memory exceptions when the DataTable is loaded from the the SqlDataReader (DatabaseGateway.GetRecords() called by ReadTrace()). I am not sure what can be easily changed to address this, since datasets are always loaded in memory.
