"overlay_segmentation"-Function is missing

[Pfleiderer-Adrian]

Hi,

the "overlay_segmentation"-Function is missing in miscnn/utils/visualizer.py which was used by the "visualize_samples"-Function.
I think the "overlay_segmentation"-Function was renamed to "overlay_segmentation_greyscale" but the references was not updated.

Regards,
Adrian
