Adds a split_test_module XModule, that can choose one of its children
to display, based on a get_condition_for_user API added to the runtime.
To test, add something like this to an xml course, or make equivalent
tweaks in mongo.
<vertical url_name="split_test_vert">
<split_test url_name="split1" experiment_id="0" condition_id_to_child='{"0": "i4x://MITx/6.00x/html/split_test_cond0", "1": "i4x://MITx/6.00x/html/split_test_cond1"}'>
<html url_name="split_test_cond0">condition 0</html>
<html url_name="split_test_cond1">condition 1</html>
</split_test>
</vertical>
Also needs an experiment configured in the course policy json: e.g.
"user_partitions": [{"id": 0,
"name": "Experiment 0",
"description": "Unicorns?",
"version": 1,
"groups": [{"id": 0,
"name": "group 0",
"version": 1},
{"id": 1,
"name": "group 1",
"version": 1}]}]
(This particular snippet will work inside a course with org MITx
and course name 6.00x)
