18.05.19 : 0.2 : first version
07.06.19 : 0.3 : removed OUTFORMAT=emuDB, since the tool does not really create an Emu DB, just 
                 a Emu DB *_annot.json file.
13.06.19 : 0.4 : added TRN output to CSV converter, even if the input BPF contains no proper hierarchy.
                 that enables conversion of Pause Detection output (TRN only)

                 extended emuR output to BPF tiers KSS and MRP; in contrast to CSV output both KAN and KSS 
                 are output, if both are present in input.
                 extended TextGrid output to BPF tiers KSS and MRP; in contrast to CSV output both KAN and KSS
                 are output, if both are present in input.

30.12.19 : 1.7 : emuDB output : if a MAS tier is converted and it contains tone markers, the tone markers are
                 purged from the MAS labels and MAS is extended by an attribute TON which contains only 
                 the tone number 1-9;
                 if a MAS and a MAU tier are converted, additional links from MAS to MAU are created.
