Updating the vignette as promised with information about dependencies. A...

...lso commented out information about the .map-file.

I am unaware of the .map-file mentioned, there is no such thing in the code. 
Is that something that should be revised eventually?

I know I am very late with this update, there have been a number of personal issues the last two years. Hope you will accept my revised manual.
