add OCR / translation
new PR as requested
I cleaned up the code, used argument lists and replaced T -> TRUE, F-> FALSE
I am aware, that I am not a good R programmer, more an R user, but I hope we can get the code in an acceptable state.
My PR is in this sense as well more a "proof of concept" then "ready made code", which demonstrate the usefullness and feasibility of the feature of automatic OCR and translation.
For my colleges this is a real time safer.
