Reader

The Reader object provides the public API for reading a NITF from file, storing the results of its read into a nitf Record. The Reader handles parsing meta-data on the initial read() method, and provides factory construction for the sub-readers (ImageReader and SegmentReader), which are, in turn, used to read their respective segments of the file. If the Reader, while parsing, encounters a TRE, it will make an appropriate call to the PluginRegistry to load the TRE handling capabilities (if they are not already loaded). If no appropriate handler can be found, the Reader will store the TRE as a singular raw data Field.
