remove unused function from heatmapper
added new line to hash labeling in output bed. Without this new line the cluster name was a mix of the actual name plus the content of the bed region that was suppose to be in the next line.
NEW: added parameter legendLocation to adjust the location of the legend in the profile plots. This applies for both heatmapper and profiler. I also improved the layout. Now in heatmapper the labels for the profile y-axis do not overlap with the contiguous plot and the y-scale is the same for all plots when not yMin and yMax are given. A larger space between the profiles and the heatmaps was added to visualize the profiles x-labels.
