Additional logging in browser console while running

[SLornieCYC]

It would be useful if additional logging could be exposed in the browser console while the tool is loading data and running the python scripts.

I tried to use the revamped 903 FE this morning and although it sat on "Running analysis, this may take some time" for over an hour there was nothing in the console log after the initial tool set-up to indicate whether it was actually still processing or had broken/got stuck somewhere. There's no way to tell if it would have finished if I'd given it just a little more time, if it had failed silently on one particular validation rule, or even if it had managed to load my files into the expected dataframes to begin with!

Another example of the problem:

• I loaded a single csv file to the 903 tool (PlacedAdoption) with 17 rows of data.
• I selected a single rule to validate (563) which only interacts with the PlacedAdoption dataframe.
• Tool has (supposedly) been running this single file and validation rule for 15 minutes.

I can't believe it should take that long, but there's no logging to help me understand where it's failing via the deployed FE.
