-//  Description: This method is called by the BamReader when an object
-//               of this type is encountered in a Bam file; it should
-//               allocate and return a new object with all the data
-//               read.
-//
-//               In the case of the PNMFileType objects, since these
-//               objects are all shared, we just pull the object from
-//               the registry.
