/**
* Performs the realisation for YES/NO types of questions. This may involve

* <em>the man <b>should give</b> the woman the flower</em> has the verb
* group indicated in <b>bold</b>. The phrase is rearranged as yes/no
* question as
* <em><b>should</b> the man <b>give</b> the woman the flower</em> with the
* subject <em>the man</em> splitting the verb group.

* @param phrase
* the <code>PhraseElement</code> representing this clause.
* @param parent
* the parent <code>SyntaxProcessor</code> that will do the
* realisation of the complementiser.
* @param realisedElement
* the current realisation of the clause.
* @param phraseFactory
* the phrase factory to be used.
* @param verbElement
* the <code>NLGElement</code> representing the verb phrase for
* this clause.
* @param subjects
* the <code>List</code> of subjects in the clause.
