*
* Interface implemented by classes, instantiations of which can serve as data models in Tetrad. Data models may be
* named if desired; if provided, these names will be used for display purposes.
*
* This interface is relatively free of methods, mainly because classes that can serve as data models in Tetrad are
* diverse, including continuous and discrete data sets, covariance and correlation matrices, graphs, and lists of other
* data models. So this is primarily a taqging interface.
