Added tests for SCXML send. Also, modified test harness to be asynchronous. New test for send doesn't pass yet.
Test send-data works after update to test harness and scion-scxml.
Added test send-internal. Renamed test group 'sendData' to 'raise'.
Added atom3-basic-tests. Created script to regenerate all tests from scion-scxml. Regenerated and re-ran all tests. All tests pass.
Regenerated all tests. Modified scion.js to fix bug with multiple transition targets, which was being tripped by more-parallel/test9.
Forgot to check in tests in more-parallel/  in previous commit.
Regenerated all tests to match new features in scion-scxml. Mostly, the getDelayInMs function is conditionally generated.
Updated tests to use new scion-scxml feature: safer early-binding datamodel initialization.
