##
# A TokenStream is a list of tokens, gathered during the parse of some entity
# (say a method). Entities populate these streams by being registered with the
# lexer. Any class can collect tokens by including TokenStream. From the
# outside, you use such an object by calling the start_collecting_tokens
# method, followed by calls to add_token and pop_token.

  # Converts +token_stream+ to HTML wrapping various tokens with

  # with the given class names. Other token types are not wrapped in spans.
