The main tool mausbpfDB2emuDB (for the DB):
- calls mausbpf2emuR

The helper tool mausbpf2emuR (to convert a single file) 
- must work independently from the main tool (because the WebAPI will 
use this to convert single files)
=> done

asrbpf2emuR should be integrated into mausbpf2emuR.
=> done

Both must cope with arbitrary BPF combinations of defined possible tiers:
header: SAM MAO SAO (we don't convert other standard header entries!)
class1: ORT KAN KAS SPK
class4: MAU MAS WOR
=> done

DBConfig and _annot structure must always match!

Concept mausbpfDB2emuDB:
- analyse presence of header, class1 and class4 tiers and build 3 arrays of keys
- use these arrys in a generic DBConfig builder to produce DBConfig
- go over input files, call mausbpf2emuR (*.par) or copy (*_annot.json)
- use schemata to check
=> done

Concept mausbpf2emuR:
- analyse presence of header, class1 and class4 tiers and build 3 arrays of keys
- use these array in a generic annot builder to produce *_annot.json
=> done

Check several BPF toer combinations 
=> done
 
Bug: ORT with word link 1 (please) wird gegen alle class 4 elemente mit word link "-1" gelinkt.
=> fixed
