Makes the given visitor visit the signature of this {@link SignatureReader}. This signature is
the one specified in the constructor (see {@link #SignatureReader}). This method is intended to
be called on a {@link SignatureReader} that was created using a <i>ClassSignature</i> (such as
the <code>signature</code> parameter of the {@link org.objectweb.asm.ClassVisitor#visit}
method) or a <i>MethodSignature</i> (such as the <code>signature</code> parameter of the {@link
org.objectweb.asm.ClassVisitor#visitMethod} method).

@param signatureVistor the visitor that must visit this signature.
