Description

I was intuitively thinking that the following code would work:

Status s;
Int64Builder builder;
s = builder.Append(1);
s = builder.Append(2);

std::shared_ptr<NumericArray<Int64Type>> array;
builder.Finish(&array);

However, it does not seem to work, as the finish operation is not overloaded in the Int64 (or the numeric builder).

Would it make sense to add this interface?
