+     Test cases for Touch Events v1 Candiate Recommendation
+     http://www.w3.org/TR/2011/CR-touch-events-20111215/
+
+     These tests are based on Mozilla-Nokia-Google's single-touch tests and to some extent Olli Pettay's multi-touch tests. 
+	 http://w3c-test.org/webevents/tests/touch-events-v1/submissions/Moz-Nok-Goog/single-touch.html
+     http://w3c-test.org/webevents/tests/touch-events-v1/submissions/Mozilla/multi-touch.html
+
+	 The primary purpose of the tests in this document is checking that the various interfaces of the Touch Events APIs are correctly implemented.
+	 Other interactions are covered in other test files.
+
+     This document references Test Assertions (abbrev TA below) written by Cathy Chan
