 calls and has to be called prior to any <tt>generate(...)</tt> calls.
 The caller of this method has to take care that:
 <ul>
 <li><tt>args.length == getInputAttributes().length</tt>, i.e. that
 the arity is correct.
 <li>The types of the example attributes match the types specified by
 <tt>getInputAttributes()</tt>.
 <li>The true attribute indices are used (as used by the example set's
 example table)

<DD>Subclasses must implement this method so that a new instance of this
 generator class is returned. The arguments and the example table will not
 be cloned and thus be null. This kind of clone is needed as generating
 algorithms must be able to clone generators form their pool without
 changing the arguments already set for the others.

<DD>Generates the new attribute values for the example e and returns the new
 attribute values as doubles. <tt>e.getAttribute(getArgument(i))</tt> is
 the correct way to access argument <i>i</i>. If the according
 attribute's type is VALUE_SERIES, the end index can be determined by
 <tt>i_end = getExampleTable().getBlockEndIndex(getArgument(i))</tt>.
 Thus all values of the series can be accessed using indices <i>i</i>
 through <i>i_end</i>.
