this is the MITK bug for creating a "light" version of the DataManager (DM). This is connected to the QA T11039. The following requirements were formulated in the course of the design:
- the DM shows all loaded images in a list
- the DM ensures that only the selected image is visible (all other images are not visible)
- the DM features loading an image from disk
- the DM enables for removing an image from the list
- the DM shows the name of the patient of the currently selected image
