Allows for concatenation of two datasets into a single, large dataset.

This is a skeleton class which provides generic superset services in terms of methods which must be implemented by subclasses. A Superset view allows two datasets to be virtually merged along their columns or rows. The dimension of the non-merged dimension must be equal. i.e. If creating a superset of rows, the datasets must have the same number of columns.

A subclass of SupersetView must implement the methods mapKeyToParent(key) and mapKeyFromParent(parent, key).
