Description:

whenever a script is encountered in a document,
an anonymous subclass of myself is created and a single instance of
it. The scripts variables are defined as instance variables, the methods
are installed as instance methods.
This is the script-object, which does all the smalltalkScript stuff.

For javaScript, the mechanism is similar, using an instance of
JavaScriptEnvironment.

Instance protocol:

 window

return the window object.
For now, that's the only defined (non-global) object.

 _evaluateAction: aString with: aComponentName

invoked when some HTML-element (such as a button) with an ONCLICK
action is pressed. This is supposed to parse the passed string as
an expression in my language (i.e. smalltalkScript) and invoke that
function.

 _setupForWindow: aWindow

invoked after creation and definition of all my methods;
this must setup the object-tree as visible to the script;
i.e. window
view
document
images
applets
forms
links
anchors
location
history
frames
This is (for now) very rudimentary.
