Detailed Description

Slight modification of TGraph where the arrays are guaranteed to be aligned properly. The wisdom of this class is questionable; in principle it might help the compiler autovectorize, but that seems like a fool's errand. For manual vectorization, it can make loads faster in certain cases (depending on the processor).

I also added a few convenience methods...

)

Create a TGraphAligned from a TGraph. Use this in case I haven't yet implemented the TGraph constructor you want; it's just an extra copy. I think this should fire also for TGraphAligned, but not sure
