Add / List / Remove global labelGroup to / of / from emuDB
Add / List / Remove label group that can be used as a short hand
to reference groups of labels that are globally defined
for the entire database (compared to attribute definition
specific label groups that
are added by add_attrDefLabelGroup) in a
query. A common example would be to
add a label group for something like the phonetic
category of nasals to be able to reference them
as "nasals" in a query.
In theory you could use a labelGroupName as a label instance within the
level, but since this could lead to serious confusion, it is better avoided.
For users transitioning from the legacy EMU system: Do not confuse a
labelGroup with legal labels: a labelGroup
had the unfortunate name 'legal labels' in the legacy EMU system.
