Quantity object does not have access to QuantitySpec object.

[Paulie14]

• root_quantity is constructed using list of QuantitySpec
• Quantity is accessed from root_quantity by quantity name

It would be nice to get from Quantity its QuantitySpec - get name, unit, time axis etc..

Currently, I have to get QuantitySpec by sample_storage.load_result_format() and search for selected quantity. When moving around, I have to pass QuantitySpec and Quantity together manually.

I created auxiliary function fot that:

    def get_quantity(self, result_format, root_quantity, quantity_name):

        iqspec, qspec = next(((i, q) for i, q in enumerate(result_format) if q.name == quantity_name), (0, None))
        assert qspec is not None

        quantity = root_quantity[quantity_name]
        return qspec, quantity
