Build hierarchy.
 This methods implements the core functionality of framework based clustering hierarchy building.
- Type Parameters:
- S- Type of structures clustered
- F- Type of frameworks associated
- Parameters:
- structures- Input structures. This- Iteratoris accessed only from the calling thread.
- frameworkAssociation- Structural framework series association. This method is expected to be thread safe
 and side effect free. This- Functionmight be accessed from other threads.
- frameworkIndex- The returned indices are used for building the clustering hierarchy. A typical
 implementation also stores the associations. The passed implementation is expected to be thread safe.
- errorHandler- Error handler. Expect errors during framework enumeration.
- po- Observer to track execution. Method- ProgressObserver.done()will be invoked upon completion.
- Returns:
- Clustering hierarchy in which the representant structure of each cluster is set to an arbitrary structure
 read; structure IDs are supplied by the passed OrderedElementinstances.
- Throws:
- LicenseException- when appropriate license is not available
- CancellationException- Upon cancellation through the given ProgressObserver
