/** \class ThreadedDomainPartitioner
* \brief Virtual base class for partitioning a domain into subsets to be
* processed per thread when parallel processing.
*
* \tparam TDomain The type of the domain to be partitioned.
*
* \c PartitionDomain is a method to split the domain into
* non-overlapping pieces for threading. It must be overridden by derived
* classes to provide the particular functionality required for
* \c TDomain type.
*
* Subclasses of this class are typically used as template arguments to a DomainThreader.

*
* This method should be called repeatedly for each value of \c threadId, from 0 up
