class Sinatra::Reloader::Watcher::List

Collection of file Watcher that can be associated with a Sinatra application. That way, we can know which files belong to a given application and which files have been modified. It also provides a mechanism to inform a Watcher of the elements defined in the file being watched and if its changes should be ignored.
