+==========================
+Surveys and Questionnaires
+==========================
+
+Let's first set up a  questionaire.
+
+  >>> from cybertools.knowledge.survey.questionnaire import Questionnaire, Question
+  >>> quest = Questionnaire()
+
+  >>> qu01 = Question(quest)
+  >>> qu02 = Question(quest)
+  >>> qu03 = Question(quest)
+
+We now assign result elements with the questions of this questionnaire.
+
+  >>> from cybertools.knowledge.survey.questionnaire import ResultElement
+  >>> re01 = ResultElement('re01')
+  >>> re02 = ResultElement('re02')
+  >>> re03 = ResultElement('re03')
+
+  >>> qu01.resultElements = {re01: 0.8, re03: 0.2}
+  >>> qu02.resultElements = {re01: 0.3, re02: 0.7, re03: 0.1}
+  >>> qu03.resultElements = {re01: 0.2, re03: 0.9}
+
+
+Responses
+---------
+
+  >>> from cybertools.knowledge.survey.questionnaire import Response
+  >>> resp01 = Response(quest, 'john')
+
+  >>> resp01.values = {qu01: 2, qu02: 1, qu03: 4}
+
+Now let's calculate the result for resp01.
+
+  >>> res = resp01.getResult()
+  >>> for re, score in res:
+  ...     print re.text, score
+  re03 4.1
+  re01 2.7
+  re02 0.7
