Comments

The LNITFFile::Create must be called before calling any other LNITFFile::XXX functions.

To create an empty NITF file, pass the pszFileName parameter as NULL.

To parse an existing NITF file, pass a valid file name to the pszFileName parameter.

To save the created NITF file, call the LNITFFile::SaveFile function.

When the class object is no longer needed, call the LNITFFile::Destroy function. For every call to LNITFFile::Create there must be a call to LNITFFile::Destroy.
