10 * Iostream is a library that implements streams, external memory
11 * sorting on streams, and an external memory priority queue on
12 * streams. These are the fundamental components used in external
13 * memory algorithms.
14
15 * Credits: The library was developed by Laura Toma. The kernel of
16 * class STREAM is based on the similar class existent in the GPL TPIE
17 * project developed at Duke University. The sorting and priority
18 * queue have been developed by Laura Toma based on communications
19 * with Rajiv Wickremesinghe. The library was developed as part of
20 * porting Terraflow to GRASS in 2001. PEARL upgrades in 2003 by
21 * Rajiv Wickremesinghe as part of the Terracost project.
