// HISTORY
// ------------------------------------------------------------------
// April 20, 2005: Fixed the removeSelectedOptions() function to 
//                 correctly handle single selects
// June 12, 2003: Modified up and down functions to support more than
//                one selected option
/*
DESCRIPTION: These are general functions to deal with and manipulate
select boxes. Also see the OptionTransfer library to more easily 
handle transferring options between two lists

COMPATABILITY: These are fairly basic functions - they should work on
all browsers that support Javascript.
