 * Represents an annotated {@link HProperty} mapping of a JavaBean java.util.Collection type property
 * to multiple indexed columns in an HBase table.  The multiple values will be mapped to columns
 * based on the value index in the collection:
 * 		[column family]:[column name]_[index number]
 * 
 * Due to the mapping to multiple columns, these property types are not easily covered by HBase 
 * secondary indexes and should not be used as query criteria.
