Add public accessor to RooPlot::_hist ?

[VanyaBelyaev]

Feature description

Would it be possible to add the public accessor to RooPlot::_hist member?
or, alternatively, provide copy-constructor for RooPlot class ?

It looks like simple action - just one pubilc inline function.
The action is 100% backward compatible, safe and should not break any existing code.

Alternatives considered

Suitable alternative (for my purpose) is the existence of enabled pubilc copy constructor for class RooPlot, that is currently explicitely disabled.
Howeevr I suspect that this alternative solutino could be more complicated - Likely there are some good reasons to disable it. e.g. related to the ownership of RooCurve/RooHist/TH1/... objects..

Well, I have no problem adding the public getter! The data member was already protected after all, which is basically public (users who want to access it can just to this over a custom derived base class).

To prevent these hacks to get the protected members in user codes, my bar for adding public getters for protected members is low.

So thanks for letting me know! Is this PR okay for you?
