A token is a (type, value) tuple, where I{type} is an int, and
I{value} is a string. The valid types are EOF, EOL, WHITESPACE,
IDENTIFIER, QUOTED_STRING, COMMENT, and DELIMITER.
@ivar file: The file to tokenize
@type file: file
@ivar ungotten_char: The most recently ungotten character, or None.
@type ungotten_char: string
@ivar ungotten_token: The most recently ungotten token, or None.
@type ungotten_token: (int, string) token tuple
@ivar multiline: The current multiline level. This value is increased
by one every time a '(' delimiter is read, and decreased by one every time
a ')' delimiter is read.
@type multiline: int
@ivar quoting: This variable is true if the tokenizer is currently
reading a quoted string.
@type quoting: bool
@ivar eof: This variable is true if the tokenizer has encountered EOF.
@type eof: bool
@ivar delimiters: The current delimiter dictionary.
@type delimiters: dict
@ivar line_number: The current line number
@type line_number: int
@ivar filename: A filename that will be returned by the L{where} method.
