+Utility functions concerned with parsing text into tokens.
+
+Most functions have the following pattern:
+
+* The parameters are:
+** `source`: the source string being parsed
+** `pos`: the current parse position within the string
+** Any further parameters are used to identify the token that is being parsed
+* The return value is:
+** null if the token was not found at the specified position
+** an object representing the token with the following standard fields:
+*** `type`: string indicating the type of the token
+*** `start`: start position of the token in the source string
+*** `end`: end position of the token in the source string
+*** Any further fields required to describe the token
+
+The exception is `skipWhiteSpace`, which just returns the position after the whitespace.
