/*
 * The Select widget is an enhanced version of HTML's <select> tag.
 *
 * Similar features:
 *   - There is a drop down list of possible values.
 *   - You can only enter a value from the drop down list.  (You can't enter an arbitrary value.)
 *   - The value submitted with the form is the hidden value (ex: CA),
       not the displayed value a.k.a. label (ex: California)
 *
 * Enhancements over plain HTML version:
 *   - If you type in some text then it will filter down the list of possible values in the drop down list.
 *   - List can be specified either as a static list or via a javascript function (that can get the list from a server)
