* \brief Wrapper for packing an arbitrary number of arguments into a single object
*
* camp::Args is defined as a list of arguments of any type (wrapped in camp::Value instances),
* which can conveniently be passed to all the CAMP entities which may need an arbitrary number of arguments
* in a uniform way.
*
* Arguments lists can be constructed on the fly using one of the constructors (accept up to 5 arguments):
*
* \code
* camp::Args args(1, true, "hello", 5.24, myObject);
* \endcode
*
* ... or appended one by one using the + and += operators:
*
* \code
* camp::Args args;
* args += 1;
* args += true;
* args += "hello";
* args += 5.24;
* args = args + myObject;
* \endcode
