Address conversion

<!-- Find the following in full-address.php: -->

<?php if( tribe_get_country( $postId ) ) { ?>
    <?php $address_out []= '<span itemprop="addressCountry">' . tribe_get_country( $postId ) . '</span>'; ?>
<?php } ?>


<!-- Replace with something like this: -->

<?php
if( tribe_get_country( $postId ) ) {
    $country = tribe_get_country( $postId );

    // A switch statement is an ungainly way of doing this, it would
    // be preferable to use a lookup table - but this gives an idea
    // of the basic mechanics
    switch ( $country ) {
        case 'Canada':
            $country = 'CA';
        break;
        case 'United States':
            $country = 'US';
        break;
    }

    $address_out []= '<span itemprop="addressCountry">' . esc_html( $country ) . '</span>';
}
?>
