Detailed Description

Proxy for an object's attribute. Instances of this class are created by the attr member function of RObject.

When the proxy is used on the lhs of an assignment it forwards the object it is assigned to to the attribute, outsourcing to wrap the job of creating the SEXP from the input type

When the proxy is used on the rhs of the assignment, it retrieves the current value of the attribute and outsources to as the job of making an object of the appropriate type
