Detailed Description

template<class Type>
class Foam::ParSortableList< Type >

Implementation of PSRS parallel sorting routine.

From "On the Versatility of Parallel Sorting by Regular Sampling" Xiaobo Li et. all.

Construct from list of things to sort (uses SortableList, 'thing' should implement >, ==).

Will contain sorted data and in

Can also be constructed from size, filled at ease and then sort()'ed.
