-/**
- * Smarty {html_select_date} plugin
- * Type:     function<br>
- * Name:     html_select_date<br>
- * Purpose:  Prints the dropdowns for date selection.
- * ChangeLog:
- * <pre>
- *            - 1.0 initial release
- *            - 1.1 added support for +/- N syntax for begin
- *              and end year values. (Monte)
- *            - 1.2 added support for yyyy-mm-dd syntax for
- *              time value. (Jan Rosier)
- *            - 1.3 added support for choosing format for
- *              month values (Gary Loescher)
- *            - 1.3.1 added support for choosing format for
- *              day values (Marcus Bointon)
- *            - 1.3.2 support negative timestamps, force year
- *              dropdown to include given date unless explicitly set (Monte)
- *            - 1.3.4 fix behaviour of 0000-00-00 00:00:00 dates to match that
- *              of 0000-00-00 dates (cybot, boots)
- *            - 2.0 complete rewrite for performance,
- *              added attributes month_names, *_id
- * </pre>

- * Smarty {html_table} function plugin
- * Type:     function<br>
- * Name:     html_table<br>
- * Date:     Feb 17, 2003<br>
- * Purpose:  make an html table from an array of data<br>
- * Params:
- * <pre>
- * - loop       - array to loop through
- * - cols       - number of columns, comma separated list of column names
- *                or array of column names
- * - rows       - number of rows
- * - table_attr - table attributes
- * - th_attr    - table heading attributes (arrays are cycled)
- * - tr_attr    - table row attributes (arrays are cycled)
- * - td_attr    - table cell attributes (arrays are cycled)
- * - trailpad   - value to pad trailing cells with
- * - caption    - text for caption element
- * - vdir       - vertical direction (default: "down", means top-to-bottom)
- * - hdir       - horizontal direction (default: "right", means left-to-right)
- * - inner      - inner loop (default "cols": print $loop line by line,
- *                $loop will be printed column by column otherwise)
- * </pre>
- * Examples:
- * <pre>
- * {table loop=$data}
- * {table loop=$data cols=4 tr_attr='"bgcolor=red"'}
- * {table loop=$data cols="first,second,third" tr_attr=$colors}
- * </pre>
