Consider the following query against a `.coverage` run against Datasette itself:

```sql
select file_id, context_id, numbits_to_nums(numbits) from line_bits
```
<img width=""1451"" alt=""_coverage__select_file_id__context_id__numbits_to_nums_numbits__from_line_bits"" src=""https://user-images.githubusercontent.com/9599/84582622-40ffc580-ada3-11ea-98d2-52bcde514a26.png"">

It looks like this tells me which lines of which files were executed during the test run. But... without the actual source code, I don't think I can calculate the coverage percentage for each file. I don't want to count comment lines or whitespace as untested for example, and I don't know how many lines were in the file.

If I'm right that it's not possible to calculate percentage coverage from just the `.coverage` data then I'll need to do something a bit more involved - maybe parsing the `coverage.xml` report and loading that into my own schema?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",638259643,Take advantage of .coverage being a SQLite database,
