Include org.simantics.threadlog by default and provide an SCL API for it
> import "Simantics/Debug/ThreadLog"
> openController
> task = begin "FOO"
> end task
openController
will open the old JFrame
UI to allow starting of logging and begin
and end
are used to start and end logging tasks.
Perhaps we should add also means to do what the controller UI does without actually opening the controller UI.
Also, we should consider consolidating the threadlogger implementation from org.simantics.utils.threads
here and support headless SVG dumping of logs.
