 /** Base class of other writers used internally.

   * This class provides the interfaces for writing files. 

   *

   * The role of the writer is to effectively "write" specific file data

   * vs the role of the exporter is to select a specific writer

   * and launch the writing of a file through that writer.

   * \see KFbxExporter 

   *

   * ex:

   * - KFbxWriterFbx  can write FBX 5 format files

   * - KFbxWriterFbx6 can write FBX 6 format files

   * - KFbxWriterFbx7 can write FBX 7 format files

   * - KFbxWriterCollada can write Collada files

   * - KFbxWriterDxf can write Dxf files

   * - ... etc.

   *

   * A SDK user should - normally - not use this class,

   * except if a custom writer must be created for plug-in extension,

   * then KFbxWriter must be the base class for 

   * the new custom writer in that particular situation.
