A tokenizerState returns a token, given a scanner, an initial character read from the scanner,
and a tokenizer that is conducting an overall tokenization of the scanner. The tokenizer will
typically have a character state table that decides which state to use, depending on an initial
character. If a single character is insufficient, a state such as SlashState
will read a second character, and may delegate to another state, such as SlashStarState.
This prospect of delegation is the reason that the nextToken()
method has a tokenizer argument.
