* MODULE: iostream
*
* COPYRIGHT (C) 2007 Laura Toma
*
*
* Iostream is a library that implements streams, external memory
* sorting on streams, and an external memory priority queue on
* streams. These are the fundamental components used in external
* memory algorithms.
* Credits: The library was developed by Laura Toma. The kernel of
* class STREAM is based on the similar class existent in the GPL TPIE
* project developed at Duke University. The sorting and priority
* queue have been developed by Laura Toma based on communications
* with Rajiv Wickremesinghe. The library was developed as part of
* porting Terraflow to GRASS in 2001. PEARL upgrades in 2003 by
* Rajiv Wickremesinghe as part of the Terracost project.
