+// AUTHOR
+//   Forrest Smith

+//   Compiling
+//     You MUST add '#define FTS_FUZZY_MATCH_IMPLEMENTATION' before including
+//     this header in ONE source file to create implementation.
+//
+//   fuzzy_match_simple(...)
+//     Returns true if each character in pattern is found sequentially within
+//     str
+//
+//   fuzzy_match(...)
+//     Returns true if pattern is found AND calculates a score.
+//     Performs exhaustive search via recursion to find all possible matches and
+//     match with highest score. Scores values have no intrinsic meaning.
+//     Possible score range is not normalized and varies with pattern. Recursion
+//     is limited internally (default=10) to prevent degenerate cases
+//     (pattern="aaaaaa" str="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa") Uses uint8_t for
+//     match indices. Therefore patterns are limited to 256 characters. Score
+//     system should be tuned for YOUR use case. Words, sentences, file names,
+//     or method names all prefer different tuning.
