* This is a controller. It links the views related to the codeviewer together with the model, which holds
6
* Function names equals path. Example: codeviewer/show in the url calls the function show in the controller
7
* codeviewer (this file below).
9
* The params after the url equals the input arguments of the function. Function show() has 3 arguments
10
* and therefore requires 3 arguments to be given in the url, like so: codeviewer/show/courseid/exampleid/pageid
12
class Codeviewer extends CI_Controller {
15
* This shows the codeviewer page
