* This is a controller. It links the views related to the codeviewer together with the model, which holds

* the logic.  

*

* Function names equals path. Example: codeviewer/show in the url calls the function show in the controller

* codeviewer (this file below).

*

* The params after the url equals the input arguments of the function. Function show() has 3 arguments

* and therefore requires 3 arguments to be given in the url, like so: codeviewer/show/courseid/exampleid/pageid
