Things were getting a little crowded in the project root, so this patch
moves the Lib*/ directories into Libraries/.

/*
The class ArgsParser provides a way to parse arguments by using a given list that describes the possible
types of arguments (name, description, required or not, must be followed by a value...).
Call the add_arg() functions to describe your arguments.
The class ArgsParserResult is used to manipulate the arguments (checking if an arg has been provided,
retrieve its value...). In case of error (missing required argument) an empty structure is returned as result.
