Skeleton of 3D plot of experimental results

To have an insight into the results from Ivans experiments I think it
would be advantageous to select the lens/sensor combination that gives
the brightest exposures and the shortest scintillator-detector distance
at the shortest exposure time.
This script will become this visualization and is based on bits and
pieces from http://matplotlib.org/mpl_toolkits/mplot3d/tutorial.html
Save final file to correct folder

And also do the final plot normally, not semi-logarithmically...
Be a bit more chatty

Being more chatty in the output and in the log file, since this is what
we need for the three dimensional view of all the data
Working visualization of parameters in 3Dplot

- We are reading the parameters from their respective log files
- Displaying the chosen parameters with a 3D scatter plot
- Further tests needed to have a *nice* visualization
Only save images if desired

Sometimes we only want the log files. Only saving the images on demand
makes the script run a bit quicker
