/**
* Useful Map that does not care about the case-sensitivity of keys
* when the key value is a String. Other key types can be used.
* String keys will be treated case insensitively, yet key case will
* be retained. Non-string keys will work as they normally would.
* <p>
* This Map uses very little memory (See CompactMap). When the Map
* has more than 'compactSize()' elements in it, the 'delegate' Map
* a LinkedHashMap.
