Explicitly define copy/move constructors for accessor

Browse Source 
`accessor` currently relies on an implicit default copy constructor, but that is deprecated in C++11 when a copy assignment operator is present and can, in some cases, raise deprecation warnings (see #888).  This commit explicitly specifies the default copy constructor and also adds a default move constructor.
