Updated Histogram2 Plotting Style
Updated Histogram2 Plotting Style

Changed default normalization to pdf
-Scales with bin size -> Smaller Bins don't reduce the pdf range of the plot
-Represents %/Area so it more intuitive to use
-ie. Intergrating over an area gives the proablity of that area

Switched to plotting the Log of the normalization
-Large range of magnitudes makes coloring the raw normalized count hard (ie. it's all one color)
-Removed countour labels and lines from plots and switched to a colorbar
