* Matrix: An example host object class that implements the Scriptable interface.

* script writer must create every array in an array of arrays. The Matrix class
* takes care of that by automatically allocating arrays for every index that
* is accessed. What's more, the Matrix constructor takes a integer argument
* that specifies the dimension of the Matrix. If m is a Matrix with dimension 3,
* then m[0] will be a Matrix with dimension 1, and m[0][0] will be an Array.
*
* Here's a shell session showing the Matrix object in action:
* <pre>
* js> defineClass("Matrix")
* js> m = new Matrix(2); <i>A constructor call, see <a href="#Matrix">Matrix</a> below.</i>
* [object Matrix] <i>The "Matrix" here comes from <a href"#getClassName">getClassName</a>.</i>
* js> version(120); <i>switch to JavaScript1.2 to see arrays better</i>
* 0
* js> m[0][0] = 3;
* 3
* js> m[0]; <i>an array was created automatically!</i>
* [3]
* js> m[1]; <i>array is created even if we don't set a value</i>
* []
* js> m.dim; <i>we can access the "dim" property</i>

/**
* Create a JavaScript function object from a Java method.
*
* <p>The <code>member</code> argument must be either a java.lang.reflect.Method
* or a java.lang.reflect.Constructor and must match one of two forms.<p>
*
* The first form is a member with zero or more parameters
* of the following types: Object, String, boolean, Scriptable,
* byte, short, int, float, or double. The Long type is not supported
* because the double representation of a long (which is the
* EMCA-mandated storage type for Numbers) may lose precision.
* If the member is a Method, the return value must be void or one
* of the types allowed for parameters.<p>
*
* The runtime will perform appropriate conversions based
* upon the type of the parameter. A parameter type of
* Object specifies that no conversions are to be done. A parameter
* of type String will use Context.toString to convert arguments.
* Similarly, parameters of type double, boolean, and Scriptable
* will cause Context.toNumber, Context.toBoolean, and
* Context.toObject, respectively, to be called.<p>
*
* If the method is not static, the Java 'this' value will
* correspond to the JavaScript 'this' value. Any attempt
* to call the function with a 'this' value that is not
* of the right Java type will result in an error.<p>
*
* The second form is the variable arguments (or "varargs")
* form. If the FunctionObject will be used as a constructor,
* the member must have the following parameters
* <pre>
* (Context cx, Object[] args, Function ctorObj,
* boolean inNewExpr)</pre>
* and if it is a Method, be static and return an Object result.<p>
*
* Otherwise, if the FunctionObject will <i>not</i> be used to define a
* constructor, the member must be a static Method with parameters
* (Context cx, Scriptable thisObj, Object[] args,
* Function funObj) </pre>
* <pre>
* and an Object result.<p>
*
* When the function varargs form is called as part of a function call,
* the <code>args</code> parameter contains the
* arguments, with <code>thisObj</code>
* set to the JavaScript 'this' value. <code>funObj</code>
* is the function object for the invoked function.<p>
*
* When the constructor varargs form is called or invoked while evaluating
* a <code>new</code> expression, <code>args</code> contains the
* arguments, <code>ctorObj</code> refers to this FunctionObject, and
* <code>inNewExpr</code> is true if and only if a <code>new</code>
* expression caused the call. This supports defining a function that
* has different behavior when called as a constructor than when
* invoked as a normal function call. (For example, the Boolean
* constructor, when called as a function,
* will convert to boolean rather than creating a new object.)<p>
*
* @param name the name of the function

* Class ImporterTopLevel
*
* This class defines a ScriptableObject that can be instantiated
* as a top-level ("global") object to provide functionality similar
* to Java's "import" statement.
* <p>
* This class can be used to create a top-level scope using the following code:
* <pre>
* Scriptable scope = cx.initStandardObjects(new ImporterTopLevel());
* </pre>
* Then JavaScript code will have access to the following methods:
* <ul>
* <li>importClass - will "import" a class by making its unqualified name
* available as a property of the top-level scope
* <li>importPackage - will "import" all the classes of the package by
* searching for unqualified names as classes qualified
* by the given package.
* </ul>
* The following code from the shell illustrates this use:
* <pre>
* js> importClass(java.io.File)
* js> f = new File('help.txt')
* help.txt
* js> importPackage(java.util)
* js> v = new Vector()
* []

* be an origin URL and/or a digital certificate.) Next it
* must be possible to get the current class context so that

* requesting a privileged action. And finally, it must be
* possible to map a class back into a security context so that
* additional classes may be defined with that security context.
* <p>
* These three pieces of functionality are encapsulated in the
