+(ii) a data container class named `ExperimentData` that stores the data measured during the execution

+(iii) an analysis class, attached to each experiment, that defines how to analyze the measured data.
 The analysis also attaches its results, such as fit results and figures, to the data container.
 \autoref{fig:framework} summarizes this framework.
 Importantly, this framework can interface with services to store, load, and share data.
