/**
 * <p>
 * This class defines a adjective phrase.  It is essentially
 * a wrapper around the <code>PhraseElement</code> class, with methods
 * for setting common constituents such as preModifier.
 * For example, the <code>setAdjective</code> method in this class sets
 * the head of the element to be the specified adjective
 * <p>
 * From an API perspective, this class is a simplified version of the AdjPhraseSpec
 * class in simplenlg V3.  It provides an alternative way for creating syntactic
 * structures, compared to directly manipulating a V4 <code>PhraseElement</code>.
 * <p>
 * Methods are provided for setting and getting the following constituents:
 * <UL>
 * <LI>PreModifier		(eg, "very")
 * <LI>Adjective        (eg, "happy")
 * </UL>
 * <p>
 * NOTE: AdjPhraseSpec do not usually have (user-set) features
 *
 * <code>AdjPhraseSpec</code> are produced by the <code>createAdjectivePhrase</code>
 * method of a <code>PhraseFactory</code>
 * </p>
