> Problem:
> When doing CSV exports many informations are generated twice. For example the function renderListRow(...) 
> and the function addToCSV(..) both call recPath(...) and makeRef(...). This leads to performance and memory 
> issues in large exports (>40000 entries).
> 
> 
> Solution:
> There should be a switch at the beginning of the function renderListRow(...) which checks if it is in CSV-mode or HTML-mode.
> See attached patch
