> Right now, the DataFileReader (DataFileStream actually) only allows one to query the
meta data of a file by issuing a key. A user who does not know what metadata may be stored
in the file, has no way to find out by getting a list/map of all there is. Perhaps we should
provide a way for the user to retrieve global metadata info to query it back for values.
> Attached a patch (initial) that simply exposes the HashMap that contains the metadata
after initialization of the data file reader.
