Example use: // create index for some data index := suffixarray.New(data) // lookup byte slice s offsets1 := index.Lookup(s, -1) // the list of all indices where s occurs in data offsets2 := index.Lookup(s, 3) // the list of at most 3 indices where s occurs in data

Index implements a suffix array for fast substring search. Bytes returns the data over which the index was created. It must not be modified. FindAllIndex returns a sorted list of non-overlapping matches of the regular expression r, where a match is a pair of indices specifying the matched slice of x.Bytes(). If n < 0, all matches are returned in successive order. Otherwise, at most n matches are returned and they may not be successive. The result is nil if there are no matches, or if n == 0. Lookup returns an unsorted list of at most n indices where the byte string s occurs in the indexed data. If n < 0, all occurrences are returned. The result is nil if s is empty, s is not found, or n == 0. Lookup time is O(log(N)*len(s) + len(result)) where N is the size of the indexed data. Read reads the index from r into x; x must not be nil. Write writes the index x to w. func New(data []byte) *Index

New creates a new Index for data. Index creation time is O(N) for N = len(data).
