// pairs in the oOptions collection/array.
//
// Parameters:
// oOptions:  any object collection or array of objects, where the i-th OPTION
//            tag would be (as a string): "<OPTION VALUE='" + oOptions[i][lbl]
//            + "'>" + oOptions[i][val] = "</OPTION>".
// lbl, val:  see oOptions
// selectTag: a js object representing a SELECT menu. For example, for
//            <SELECT id="123"> you would pass in ${"123"} (using prototype).
// noneLabel,
// noneValue: If oOptions is empty, then the select menu is populated
//            with a single <OPTION> tag whose value is noneValue, and whose
//            content is noneLabel.
//
// Example use with prototype Ajax:
//    onComplete: function(req) {
//      populateSelectTag(eval(req), "commodityName", "commodityId", selectTag, "None", "0" )
//    }
