BaseRegionMap consolidates common behaviour between {@link AbstractRegionMap} and
{@link ProxyRegionMap}. {@link AbstractRegionMap} should be extended when implementing
a new {@link RegionMap} and {@link ProxyRegionMap} should be used if an empty {@link RegionMap}
for regions whose DataPolicy is Proxy is required.
