> As a corollary to {{defaultString}} and similar methods, which allow the client to replace
a missing string with something, it would sometimes be helpful to have methods that enhance
a string, if it is present, with a prefix and suffix (or perhaps with an arbitrary function).
> Eg
> {code}
> if (StringUtils.isNotEmpty(queryString)) {
>     return url + "?" + queryString;
> } else {
>     return url;
> }
> {code}
> would become:
> {code}
> return url + StringUtils.addIfNotEmpty(queryString, "?", null);
> {code}
> with the second parameter being the prefix, and the third, the suffix. If the string
is null or empty, return empty string.
> If this could accept arbitrary transformation functions, it could effectively become
the Elvis operator.
