Reference counted extension which has a pointer to and owns a user defined TObject.

This class can be used as model for a reference counted derivation from TGeoExtension.

Note: Creating a TGeoRCExtension with new() automatically grabs it, but the creator has to Release it before the pointer gets out of scope. The following sequence is valid:

// producer:
TGeoRCExtension *ext = new TGeoRCExtension();
some_TGeoVolume->SetUserExtension(ext);
ext->Release();
// user:
TGeoRCExtension *ext = dynamic_cast<TGeoRCExtension*>(some_TGeoVolume->GrabUserExtension());
// ... use extension
ext->Release();

The extension is going to be released by the TGeoVolume holder at the destruction or when calling SetUserExtension(0).

The following usage is not correct:

some_TGeoVolume->SetUserExtension(new TGeoRCExtension())

since the producer code does not release the extension. One cannot call directly "delete ext" nor allocate an extension on the stack, since the destructor is protected. Use Release instead.
