3.2 Add input editor
IEditorInput serves as the model for the editor and is supposed to be a light-weight representation of the model. For example the Eclipse IDE uses this concept to identify files without handling with the complete file. Based on the equals method the system will determine if the corresponding editor is already open or not therefore you should overwrite the method equals and hashcode in an implementation of IEditor.
Create the new class <code>''MyStudentEditorInput''</code> which implements <code>''IEditorInput''</code>.
