Make it easier to analyze reports

[mgifford]

I created another script to help analyze the reports.

Right now if you scan a few sites with Purple A11y's CLI tool you'll be left with bunch of directories with HTML and CSV files in them. That's great, however it doesn't allow you to really gather the metadata behind the scan. I wanted a snapshot and not the detailed reports.

So I created a little script to crawl the CSV files and extract some very basic information that would be a very basic status report.

I wanted a consistent benchmark for our sites that allows us to demonstrate improvement over time. Seeing the individual errors is useful, but if I have scanned 1000 pages, it would make sense that there would be more errors than if I'd just scanned 100.

Knowing how many URLs, WCAG errors (for each type), axe impact status (for each type) gives a better snapshot.

Perfection is nice, but for most sites that may be unattainable, and it would be better to strive to be able to prove progress,

So I've pulled the data from the .csv files in https://github.com/mgifford/purple-a11y/blob/master/sitemap-tools/find-score.py

I've then calculated the total in https://github.com/mgifford/purple-a11y/blob/master/sitemap-tools/calculate-score.py

But generally I just run https://github.com/mgifford/purple-a11y/blob/master/sitemap-tools/run-both-scores.sh to access both.

By default, the script will hit those Purple A11y reports that have been created today.
