Make dbc work better with Jupyter notebooks #199
Description
When dbc executed in a Jupyter notebook with the !/%system, it produces a huge stream of output:
(this goes on and on and on)
It would be nice if we could show the progress in a way that's compatible with Jupyter. Short of that, we could detect we're in a notebook and use the same logic we already use in main.go to detect if we're in a TTY to at least improve the output.
