Signals are for ill-defined measurements.
Unit groups exist for two reasons:
1. To pick an appropriate unit for a type of measurement. For example,
ºC for temperatures.
2. To pick an appropriate format and label.
Signals don't fit neatly into these reasons. They don't take a unit, and
it's not obvious what format and what label they should use. So, they were
left out of units.py and defaults.py.
You can use the signal types without adding them to a unit group. You just
won't be able to convert them to a different unit (which they don't have
anyway), and there will be no automatic formatting and labelling. If you
need a format, use a .format() suffix. If you need a format, just add it
on. For example:
*$current.signal1.format("%d") widgets*
Alternatively, if your signal is actually some kind of counter, you could
assign them to group_count. Then they would use "%d" for the format, and an
empty string for the label.
