-//
-// this script is one portion of a search system. it is the brain for an object

-// note by fred huffhines:
-// much of this script was originally written by the attributed authors above. however,
-// i have spent a ton of time improving this pair of scripts... (the brain and the
-// search pointer). i've added pattern matching (rather than needing to know exact
-// names), added the spiral search traversal method to improve search behavior and
-// get more results, improved the particle streams, and other bits. i just recently added
-// configurability from notecards for searchbert options and a menuing system to provide
-// help and runtime control over some of the options. wheeee, it's been a lot of fun.
