Need a command-line version

It would be cool if there was a command-line version that output information the same way as Microsoft's metrics.exe so that this tool can be swapped with minimal changes.

Also would be good to have "class coupling" added, by Microsoft's definition, but be able to configure it to make more sense. For instance, referencing interfaces, enums should count as coupling. Also, because this tool uses Roslyn, it wouldn't include types automatically create by C# such as hidden ones necessary for lambda and LINQ, and field initializers that inject code into the constructor.
