 * This is the main url->function dispatching data struct.
 *
 * In short, it's a struct with various URLs plus their handlers. The handlers can
 * be 'standard' CGI functions you wrote, or 'special' CGIs requiring an argument.
 * They can also be auth-functions. An asterisk will match any url starting with
 * everything before the asterisks; "*" matches everything. The list will be
 * handled top-down, so make sure to put more specific rules above the more
 * general ones. Authorization things (like authBasic) act as a 'barrier' and
 * should be placed above the URLs they protect.
