/** \class ThreadedIndexedContainerPartitioner
* \brief Partitions an indexed container.
*
* The \c DomainType is defined to be a two element itk::Index of ElementIdentifiers:
* the first element defines the start of the domain, and the second element
* defines the end of the domain.
*
* Element counting starts from zero and the identifier at the end of the domain
* is inclusive.
*
* This class is typically used as a template argument to a DomainThreader.
