func NGrams(tokens []string, minN, maxN int) []uint32

Returns hashes of all N-grams in tokens with minN ≤ N ≤ maxN.

The hash of an N-gram is the hash of the tokens, joined by NUL characters. We assume these don't occur in text. The hash function used is FNV-32.

type HashPos struct {
	Hash       uint32
	Start, End int
}

Hash of n-gram at position Start through End (exclusive) in the input.

The length of input n-gram is (End-Start).

func NGramsPos(tokens []string, maxN int) []HashPos

Like NGrams, but returns position info and minN is hardcoded to one.
