The file `.toxic.json` is supposed to list egregious functions -- any change
to these functions should produce extra comments/suggestsions.

The current list is a few years old, so I've run `pdepend` and updated the list.
The list includes anything which matches one or more of these:

 * "Non Comment Lines of Code" (`ncloc`) greater than 300.
 * "[NPath](https://modess.io/npath-complexity-cyclomatic-complexity-explained/) complexity" (`npath`) greater than 1 billion.
