/**
 * A case-insensitive Map implementation that uses a compact internal representation
 * for small maps.  This Map exists to simplify JSON serialization. No custom reader nor
 * writer is needed to serialize this map.  It is a drop-in replacement for HashMap if
 * you want case-insensitive behavior for String keys and compactness.
 *
 * This creates a CompactMap with:
 * 
 *   compactSize = 50 (same as CompactCIHashMap)
 *   caseSensitive = false (case-insensitive behavior)
 *   ordering = UNORDERED (standard HashMap behavior)
 * 
 * 
 *
 * @param  the type of keys maintained by this map
 * @param  the type of mapped values
