Re: [collections] CaseInsensitiveHashMap

[Brian S O'Neill]

This implementation converts the key to lowercase on every get and put, 
which adds a bit of object allocation overhead. Also, simply converting 
to lowercase does not make it fully case-insensitive. There is a comment 
in String.regionMatches that brings up something about the Georgian 
alphabet.

What I always do when I want a case-insensitive map is to construct a 
TreeMap with String.CASE_INSENSITIVE_ORDER.

A few weeks back, David Graham submitted code for a

This looks like a good addition to [collections] to me.

Any objections to my coding up some tests and adding this class to the 
map package?
