Re-added the dev-master branch alias.
Added the missing new classes to the README file.
Added the Scrutinizer badge to the README file.
Added a Features & Roadmap section to the README file.
Splitted some functions to reduce the complexity of the functions.
Added the Traversor class to handle array loop manipulation.
It is silly to have a Traversor that does nothing. Enforce a callable for itemCallback.
Invert the resultCallback parameters to allow only for result array when we don't need the original array.
Added the Traversor class to the features & roadmap section of the README file.
Renamed the Features & Roadmap section only to Roadmap in the README file.
