stop recording if disk is almost full
better algorithm to detect disk-usage

f_bavail gives us the available blocks, which might

mroe things todo
initialize systemhealth with output-path

because that's the path we want to monitor
do not send info to SMi.pd if it is not available
things done
only stop recording if it is running
doc on basic-state OSC-messages

/mode & /process are now in both directions
use self.settings['/mode'] rather than self.mode

only keep the info in one place!
report the current mode to WILMix
transmit current mode, process-state and pd-state

/mode: streaming, recording, processing,...
/state: running or not
/state/process: Pd started/stopped (this has changed from /state)
less verbosity, more documentation
report the current processing state to WILMix
