<P>
This is interface that all objects in JavaScript must implement.
 The interface provides for the management of properties and for
 performing conversions.
 <p>
 Host system implementors may find it easier to extend the ScriptableObject
 class rather than implementing Scriptable when writing host objects.
 <p>
 There are many static methods defined in ScriptableObject that perform
 the multiple calls to the Scriptable interface needed in order to
 manipulate properties in prototype chains.

<DL>
<DD>Sets a named property in this object.
 <p>
 The property is specified by a string name
 as defined for <code>get</code>.
 <p>
 The possible values that may be passed in are as defined for
 <code>get</code>. A class that implements this method may choose
 to ignore calls to set certain properties, in which case those
 properties are effectively read-only.<p>
 For properties defined in a prototype chain,
 use <code>putProperty</code> in ScriptableObject. <p>
 Note that if a property <i>a</i> is defined in the prototype <i>p</i>
 of an object <i>o</i>, then evaluating <code>o.a = 23</code> will cause
 <code>set</code> to be called on the prototype <i>p</i> with
 <i>o</i> as the  <i>start</i> parameter.
 To preserve JavaScript semantics, it is the Scriptable
 object's responsibility to modify <i>o</i>. <p>
 This design allows properties to be defined in prototypes and implemented
 in terms of getters and setters of Java values without consuming slots
 in each instance.<p>
 <p>
 The values that may be set are limited to the following:
 <UL>
 <LI>java.lang.Boolean objects</LI>
 <LI>java.lang.String objects</LI>
 <LI>java.lang.Number objects</LI>
 <LI>org.mozilla.javascript.Scriptable objects</LI>
 <LI>null</LI>
 <LI>The value returned by Context.getUndefinedValue()</LI>
 </UL><p>
 Arbitrary Java objects may be wrapped in a Scriptable by first calling
 <code>Context.toObject</code>. This allows the property of a JavaScript
 object to contain an arbitrary Java object as a value.<p>
 Note that <code>has</code> will be called by the runtime first before
 <code>set</code> is called to determine in which object the
 property is defined.
 Note that this method is not expected to traverse the prototype chain,
 which is different from the ECMA [[Put]] operation.
