--Scroll List Control
--A scrollable list of controls that reuses controls as they scroll out of view.
--Use this control when you have a very large number of a couple different types of controls to display.
--To use:
--(1) Add a scroll list to your XML.
--(2) Add data types to the scroll list, one for each type of control. A data type includes an XML control template, a height, and a callback that can setup the control given data.
--(3) Add data to the scroll list. First, use GetDataList to get the table holding the data. Next, use CreateDataEntry to create a list element of a certain data type. You may pass
-- in an arbitrary piece of data that will be given to the setup callback when the control is shown. Once you have made as many data entries as you need, add them to the data
-- list in any way you want. Finally, call Commit to update the scroll list with your data.
-- Note: The scroll list can use faster update logic if all controls are the same height.
