Improve survey functionality

Problem Description

Expertiza used to have functionality for conducting surveys. It needs to be improved so that the data collected from the survey can be stored in the database along with course and assignment information.

Types of Surveys

Course Survey:

All the participants in a course can take the course survey. File: course_evaluation_questionnarire.rb

Global Survey:

Any Expertiza user can take the global survey. File: global_survey_questionnaire.rb

Targeted Survey:

The admin can create a survey targeted to a specific group of people. File: survey_questionnaire.rb

Requirements

Requirements:

1) A page to show the distribution of results for all types of questionnaires.

2) Use of inheritance so that survey questionnaire is a subclass of questionnaire. Also, course evaluation questionnaire and global survey questionnaire should be subclasses of survey questionnaire.

3) Use response_controller to implement the survey functionality. This should be similar to how other questionnaires like the peer review questionnaire, are implemented.

4) Use the same code to display existing survey responses as to display the responses in peer reviews.

5) For each course or assignment, the admin/instructor should be able to create a survey and have some (or all) of the participants receive the survey. The instructor should have the option to not include some questions from a global survey. The quiz takers can take the global survey and course survey consecutively.

6) An entry in the participants table called a survey_participant record must be added to indicate when a user is assigned to take part in a survey.

7) Tests need to be written for the feature.

DB Schema:

Add survey_participant to the participants table.
