Overview
This class finds target files to inspect by scanning the directory tree and picking ruby files.

#find(args) ⇒ Array
Generate a list of target files by expanding globbing patterns (if any). If args is empty, recursively find all Ruby source files under the current directory

#target_files_in_dir(base_dir = Dir.pwd) ⇒ Array
Finds all Ruby source files under the current or other supplied
directory. A Ruby source file is defined as a file with the .rb
extension or a file with no extension that has a ruby shebang line
as its first line.
It is possible to specify includes and excludes using the config file,
so you can include other Ruby files like Rakefiles and gemspecs.
