<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.

<DL>
<DD>Removes a property from this object.
 This operation corresponds to the ECMA [[Delete]] except that
 the no result is returned. The runtime will guarantee that this
 method is called only if the property exists. After this method
 is called, the runtime will call Scriptable.has to see if the
 property has been removed in order to determine the boolean
 result of the delete operator as defined by ECMA 11.4.1.
 <p>
 A property can be made permanent by ignoring calls to remove
 it.<p>
 The property is specified by a String name
 as defined for <code>get</code>.

 To delete properties defined in a prototype chain,
 see deleteProperty in ScriptableObject.

 detail.
