 * Methods for writing SBML to files and text strings.
 * <p>
 * <em style='color: #555'>
This class of objects is defined by libSBML only and has no direct
equivalent in terms of SBML components.  This class is not prescribed by
the SBML specifications, although it is used to implement features
defined in SBML.
</em>

 * <p>
 * The {@link SBMLWriter} class is the converse of {@link SBMLReader}, and provides the
 * main interface for serializing SBML models into XML and writing the
 * result to files and text strings.  The methods for writing SBML all take
 * an {@link SBMLDocument} object and a destination.  They return a boolean value
 * to indicate success or failure.

  /**
   * Equality comparison method for SBMLWriter.
   * <p>
   * Because the Java methods for libSBML are actually wrappers around code
   * implemented in C++ and C, certain operations will not behave as
   * expected.  Equality comparison is one such case.  An instance of a
   * libSBML object class is actually a <em>proxy object</em>
   * wrapping the real underlying C/C++ object.  The normal <code>==</code>
   * equality operator in Java will <em>only compare the Java proxy objects</em>,
   * not the underlying native object.  The result is almost never what you
   * want in practical situations.  Unfortunately, Java does not provide a
   * way to override <code>==</code>.
   *  <p>
   * The alternative that must be followed is to use the
   * <code>equals()</code> method.  The <code>equals</code> method on this
   * class overrides the default java.lang.Object one, and performs an
   * intelligent comparison of instances of objects of this class.  The
   * result is an assessment of whether two libSBML Java objects are truly 
   * the same underlying native-code objects.
   *  <p>
   * The use of this method in practice is the same as the use of any other
   * Java <code>equals</code> method.  For example,
   * <em>a</em><code>.equals(</code><em>b</em><code>)</code> returns
   * <code>true</code> if <em>a</em> and <em>b</em> are references to the
   * same underlying object.
   *
   * @param sb a reference to an object to which the current object
   * instance will be compared
   *
   * @return <code>true</code> if <code>sb</code> refers to the same underlying 
   * native object as this one, <code>false</code> otherwise

   * Writes the given SBML document to filename.

   * If the given filename ends with the suffix <code>'</code>.gz' (for example,

   * written compressed in <em>gzip</em>.  Similarly, if the given filename ends
   * with <code>'</code>.zip' or <code>'</code>.bz2', libSBML assumes the caller wants the file
   * to be compressed in <em>zip</em> or <em>bzip2</em> format (respectively).  Files
   * whose names lack these suffixes will be written uncompressed.
   * <em>Special considerations for the zip format</em>: If the given
   * filename ends with <code>'</code>.zip', the file placed in the zip archive will
   * have the suffix <code>'</code>.xml' or <code>'</code>.sbml'.  For example, the file in
   * the zip archive will be named <code>'test</code>.xml' if the given filename is

   * archive will be <code>'test</code>.sbml' if the given filename is 
   * <code>'test</code>.sbml.zip'.
   * <p>
   * @note To write a gzip/zip file, libSBML needs to be configured and

   * unreadable files will be logged and this method will return <code>false</code>
