 // A frame for simple tokenizers. Takes care of newlines and
 // white-space, and of getting the text from the source stream into
 // the token object. A state is a function of two arguments -- a
 // string stream and a setState function. The second can be used to
 // change the tokenizer's state, and can be ignored for stateless
 // tokenizers. This function should advance the stream over a token
 // and return a string or object containing information about the next
 // token, or null to pass and have the (new) state be called to finish
 // the token. When a string is given, it is wrapped in a {style, type}
 // object. In the resulting object, the characters consumed are stored
