TokenIterator class

Iterator that turns SGF input text into a stream of tokens.

Whitespace is skipped. Parentheses, semicolons, property identifiers, and bracketed property values are recognized. Property values follow SGF's backslash-escape rules and may contain ] and newlines as part of a single token.
