Example 1
/**

 *
 * @param v must be a member of a structure
 * @param section the requested variable section, as a List of type Range
 * @param dataV the dataDDS has been parsed into this dodsV, this is the top variable containing v
 * @param flatten if true, remove the StructureData "wrapper".
 * @return the data as as Array
 * @throws IOException on io error
 * @throws DAP2Exception on bad things happening
