/**
 * @class LocalRegion LocalRegion.hpp
 *
 * This class manages subregions and cached data. Each region
 * can contain multiple subregions and entries for data.
 * Regions provide a hierachical name space
 * within the cache. Also, a region can be used to group cached
 * objects for management purposes.
 *
 * The Region interface basically contains two set of APIs: Region management
 * APIs; and (potentially) distributed operations on entries. Non-distributed
 * operations on entries  are provided by <code>RegionEntry</code>.
 *
 * Each <code>Cache</code>  defines regions called the root regions.
 * User applications can use the root regions to create subregions
 * for isolated name space and object grouping.
 *
 * A region's name can be any String except that it should not contain
 * the region name separator, a forward slash (/).
 *
 * <code>Regions</code>  can be referenced by a relative path name from any
 * region
 * higher in the hierarchy in {@link Region::getSubregion}. You can get the
 * relative
 * path from the root region with {@link Region::getFullPath}. The name
 * separator is used to concatenate all the region names together from the root,
 * starting with the root's subregions.
