// This class functions as an adapter from a RemoveRowsTableModel to a Cocoa
// NSArrayController, to be used with bindings.
// It maps the CanRemoveRows method to its canRemove property, and exposes
// RemoveRows and RemoveAll as actions (remove: and removeAll:).
// If the table model has groups, these are inserted into the list of arranged
// objects as group rows.
// The designated initializer is the same as for NSArrayController,
// initWithContent:, but usually this class is instantiated from a nib file.
// Clicking on a group row selects all rows belonging to that group, like it
// does in a Windows table_view.
// In order to show group rows, this class must be the delegate of the
// NSTableView.

// Bind this controller to the given model.
// |columns| is a dictionary mapping table column bindings to NSNumbers
// containing the column identifier in the TableModel.
// |groupTitleColumn| is the column in the table that should display the group
// title for a group row, usually the first column. If the model doesn't have
// groups, it can be nil.
