Subclassing SLExpandableTableView while implementing delegate and datasource causes problems.

[123kyky]

Example:
class TestTableView: SLExpandableTableView, SLExpandableTableViewDelegate, SLExpandableTableViewDatasource
Looks to be the appropriate way to implement UITableView Delegate and DataSource but unable to set them.
testTableView.delegate = testTableView wants me to impossibly cast to SLExpandableDelegate

Or implementing the following also creates an error
class TestTableView: SLExpandableTableView, UITableViewDelegate, UITableViewDataSource
