**List of sources to run Ameba on can be configured globally via:**
- `Globs` section - an array of wildcards (or paths) to include to the
inspection. Defaults to `%w(**/*.cr !lib)`, meaning it includes all project
inspection. Defaults to `%w[**/*.cr !lib]`, meaning it includes all project
files with `*.cr` extension except those which exist in `lib` folder.
- `Excluded` section - an array of wildcards (or paths) to exclude from the
source list defined by `Globs`. Defaults to an empty array.
