Stable release

For this release we mostly changed the behavior of the heatmapper. Before, the creation of the underlying matrix (a slow process) and the visualization were done together. However, most of the time the visualization required adjustments, for example to try different color combinations. Because of this we separated the creation of the matrix and the plotting of the data. Moreover we added a tool only for plotting a profile. This was also part of the heatmapper before but the number of options was growing too much and we decided it was better to divide the functionality.

Also, we changed the original names of several functions to better reflect their functionality.
