/* StringSorterLexicoCaseInsensitive.java

** purpose of defining/implementing an ordering on strings.  Here,
** that is what one might call "case-insensitive lexicographic ordering",
** meaning the usual lexicographic ordering, but treating the lower-
** and upper-case versions of letters to be equal.

   ** should be considered to be equal to each other, so that
   ** 'A' = 'a' < 'B' = 'b' < ... 'y' < 'Z' = 'z'.
   ** (Thus, for example, "alligator" < "Zebra" according to this
   ** ordering, contrary to case-sensitive lexicographic ordering.)
