 * Main club presidents shortcode function
 *
 * This function displays a grid of club presidents retrieved from DACdb.
 * It can be used with the shortcode [dacdb_plus show=club_presidents]
 *
 * Supported shortcode attributes:
 * - columns: Number of presidents to display per row (1-4) - recommended standard attribute
 * - per_row: Alternative name for 'columns' attribute
 * - presidents_per_row: Legacy attribute for number of presidents per row
 * - club_presidents_per_row: Legacy attribute matching the option name
 *
 * Example usage:
 * [dacdb_plus show=club_presidents columns=1] - Display presidents in a single column
 * [dacdb_plus show=club_presidents columns=2] - Display presidents in two columns
 *
 * If no attributes are specified, the function uses the global plugin setting for 'club_presidents_per_row'.
 *
 * @param array $atts Shortcode attributes
 * @return string HTML output
