Libraries: Create top level directory for libraries.
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.
