This is used to run a LowEndInsight scanner against a project.

#Usage

mix lei.scan

This will return a basic list of reports in JSON format. LowEndInsight will scan the mix.exs file for the list of dependencies, enumerating through them and fetching the source repo URL from the Hex.pm API. Then the scanner passes that URL to LowEndInsight which does a temporary clone to perform its analysis of each dependency.
