/**
* Display or retrieve page title for category archive.
*
* This is useful for category template file or files, because it is optimized
* for category page title and with less overhead than {@link wp_title()}.
*
* It does not support placing the separator after the title, but by leaving the
* prefix parameter empty, you can set the title separator manually. The prefix
* does not automatically place a space between the prefix, so if there should
* be a space, the parameter value will need to have it at the end.
*
* @since 0.71
*
* @param string $prefix Optional. What to display before the title.
* @param bool $display Optional, default is true. Whether to display or retrieve title.
* @return string|null Title when retrieving, null when displaying or failure.
