Create plots for the Density_As_MR_Model strategy

Possible plots, including log_graphs available from phaser_tng

1. In the map boxing step (box), there is a scaling of the data to the map, and a few log_graphs are written:

       LOGGRAPH.graph[0] = "Average Intensity of Map vs Resolution:AUTO:1,3";
        LOGGRAPH.graph[1] = "Average Intensity of Data vs Resolution:AUTO:1,4";
        LOGGRAPH.graph[2] = "Ratio of Map and Data Intensity vs Resolution:AUTO:1,5";
        logGraph(out::LOGFILE,LOGGRAPH);

2. In the map weight analysis step (mwa), even if the log shows some data as in a kind of text histogram there are not logGraphs written.

3. In the map preparation step (map),also no loggraph
