/**
 * CubeRegion models a sub-unit of a Cube of the same dimensionality as the Cube
 * itself, with each Dimension optionally subsetted in its list of members.
 *
 *
 *
 * When mapped to its physical source, a CubeRegion contains data cells identified
 * by the member combinations of the Cartesian product of the CubeRegion's
 * associated Dimensions and Measures.
 *
 *
 *
 * The relative ordering of CubeDeployment classes optionally implies a desired
 * order of selection of the CubeDeployments, based on implementation-specific
 * considerations (e.g., optimized access of aggregate data).
 *
 *
 *
 * Synonyms: Sub-Cube, Partition, Slice, Region, Area.
 *
 *
 *
 * Misc. notes:
 *
 * 1.  A CubeRegion is not a Cube, and a Cube is not a CubeRegion.
 *
 * 2.  A Cube has a Measure and CubeRegion may have a corresponding measure
 * (Measures are Attributes).
 *
 * 3.  A Cube may or may not have CubeRegions.
 *
 * 4.  If a Cube does not have a CubeRegion, then it's not physically mapped (it's
 * virtual).  All physical mapping is based on the CubeRegion , not the Cube.
