/**
* An object reference managed by the v8 garbage collector.
*
* All objects returned from v8 have to be tracked by the garbage
* collector so that it knows that the objects are still alive. Also,
* because the garbage collector may move objects, it is unsafe to
* point directly to an object. Instead, all objects are stored in
* handles which are known by the garbage collector and updated
* whenever an object moves. Handles should always be passed by value
* (except in cases like out-parameters) and they should never be
* allocated on the heap.
*
* There are two types of handles: local and persistent handles.
*
* Local handles are light-weight and transient and typically used in
* local operations. They are managed by HandleScopes. That means that a
* HandleScope must exist on the stack when they are created and that they are
* only valid inside of the HandleScope active during their creation.
* For passing a local handle to an outer HandleScope, an EscapableHandleScope
* and its Escape() method must be used.
*
* Persistent handles can be used when storing objects across several
* independent operations and have to be explicitly deallocated when they're no
* longer used.
*
* It is safe to extract the object stored in the handle by
* dereferencing the handle (for instance, to extract the Object* from
* a Local<Object>); the value will still be governed by a handle
* behind the scenes and the same rules apply to these values as to
* their handles.
