Description

Add APIs:

• Add APIs StringUtils.wrapIfMissing(String, char)
• Add APIs StringUtils.wrapIfMissing(String, String)

Note: We already have:

• StringUtils.wrap(String, char)
• StringUtils.wrap(String, String)

And we already use the "IfMissing" name segment in "appendIfMissing()" and "prependIfMissing()".

Using "IfAbsent" would have been a better choice IMO since the JRE already uses "IfAbsent" in ConcurrentHashMap for example; but consistency is better here I think.
