-// A framework 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
-// under the content property. Any whitespace following them is also
-// automatically consumed, and added to the value property. (Thus,
-// content is the actual meaningful part of the token, while value
-// contains all the text it spans.)
