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)
20.06.19 : 0.5 : extended CSV output to 12 columns by adding column 'MRP' (morphological segmentation)
                 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.  
12.09.19 : 0.6 : added output format EAF
20.09.19 : 1.0 : added option '--listOutFormats'
02.10.19 : 1.1 : added option '--listOutExtensions' : parallel list to '--listOutFormats' with standard extensions.
02.10.19 : 1.2 : added option OUTFORMAT=emuDB as alias to emuR
22.11.19 : 1.5 : added output format EXB (Exmeralda)
22.12.19 : 1.6 : added output format Iso TEI
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.
18.01.20 : 1.8 : emuDB output : tone markers are removed from MAU tier labels
30.01.20 : 1.9 : emuDB output : bug fix : class 2 tiers (SPD IPA..) were not handled in mausbpfDB2emuRDB; this was a mismatch between mausbpf2emuR and mausbpfDB2emuRDB.
04.02.20 : 1.10 : TextGrid, emuDB, csv output : added VAD support
31.03.20 : 1.11 : emuDB output : patched class 4 tiers with gaps with empty-labelled segments
10.05.20 : 1.12 : emuDB output 5.54 : bug in handling links from MAS to MAU for blank-separated MAS labels (pho2syl 1.29)
25.05.20 : 1.13 : changed option name OUTFORMAT to outFormat to prevent the BAS Webservices to produce a emuDB in the ZIP Download
20.10.20 : 1.14 : emuDB output : corrupt input files that cannot be converted do no longer cause an ERROR but a WARNING
                  and are skipped for the emuDB build; all WARNINGS of the converter are logged in the file 
                  mausbpfDB2emuDBErrorLog.txt in the root dir of the result emuDB
