ClassGroup Interface
Deprecated in 5.2 - will not be removed until after 2026-10-01. Use the new @itwin/presentation-hierarchies
package for creating hierarchies.
Base class grouping allows grouping ECInstance nodes by their base class (as opposed to the hierarchy
specifications' groupByClass attribute, which always groups by direct class).
@see Base class grouping documentation section
