def DybDbiPre::ccsv::ccsv_parse	(		ccsv,
			dialect = psv
	)

Parse compound-csv strings into a list of dicts (one for each csv line)

Compound-csv format comprises standard csv (with 1 line fieldname header)
separated by lines containing only ";" 

     * whitespace at front and back of keys and values is stripped              
     * lines starting with # are regarded as ignored

TODO : improve robustness ...
     
  * trailing spaces after the ";" cause parse errors, as those 
    spaces are taken to be the fieldspec yielding::
        
       AttributeError: 'NoneType' object has no attribute 'strip'
