/**

	Set the namespace (context) of the current scope.
	<p/>

The following example illustrates swapping the current namespace.
<p/>

<pre>
fooState = object(); 
barState = object(); 

print(this.namespace);
setNameSpace(fooState.namespace);
print(this.namespace);
a=5;
setNameSpace(barState.namespace);
print(this.namespace);
a=6;

setNameSpace(fooState.namespace);
print(this.namespace);
print(a);  // 5

setNameSpace(barState.namespace);
print(this.namespace);
print(a); // 6
</pre>
<p/>

You could use this to creats the effect of a static namespace for a
method by explicitly setting the namespace upon entry.
