Get objects from AWS S3

Continue to work on pulling and pushing objects into S3 aws so here is a quick and dirty code cannibalize around...

        /* To use a variable in this script, first ensure that the variable has been added to
         * either the list contained in the ReadOnlyVariables property or the list contained in
         * the ReadWriteVariables property of this script task, according to whether or not your
         * code needs to write to the variable.  To add the variable, save this script, close this instance of
         * Visual Studio, and update the ReadOnlyVariables and
         * ReadWriteVariables properties in the Script Transformation Editor window.
         * To use a parameter in this script, follow the same steps. Parameters are always read-only.
         *
         * Example of reading from a variable:
         *  DateTime startTime = (DateTime) Dts.Variables["System::StartTime"].Value;
         *
         * Example of writing to a variable:
         *  Dts.Variables["User::myStringVariable"].Value = "new value";
         *
         * Example of reading from a package parameter:
         *  int batchId = (int) Dts.Variables["$Package::batchId"].Value;
         * 
         * Example of reading from a project parameter:
         *  int batchId = (int) Dts.Variables["$Project::batchId"].Value;
         *
         * Example of reading from a sensitive project parameter:
         *  int batchId = (int) Dts.Variables["$Project::batchId"].GetSensitiveValue();
