Added files:
/modules/matthew/newrat Container.js notes.txt
Modified files:
/modules/matthew/newrat DisplayManager.js Item.js Page.js
Resource.js Sequence.js assembler.pl
overview.js test.js
Log:
To see the "progress", run ./assembler.pl and point your web browser
at ./simple_rat.html.
Sequence and Page objects are now descendents of a new Container object,
instead of being descendents of Item. Added 'edit' mode for drawing items.
notes.txt contains random (rat-related) thoughts. overview.js was updated
to include a little verbage about the Container object and the descriptions
of the other guys (Item and Display Manager (still ficticious, but there is
always some hope)) was updated.

open simple_rat.html in your web browser to see what's going on.
Sequences need to assign id's automagically:
manage an array of used ids
take care of reassigning them when items are deleted.
undo/redo need to be carefully thought out....
load/save also need to be thought out.
unit tests need to be developed
insert, remove, moveup, movedown, add_parm, change_parm, etc.
All of the interface commands for Conditional and Item must be tested
in each of their implementations.
The tests must be run on each of the platforms
Display Manager needs to be set up - I need to be able to monitor events
can I automatically detect changes in my forms? Will
onblur="javascript:dispatchevent('eventstring')"
work for NS4.x,6.2,mozilla, IE4.05,4.5,5.x, mac, windows, linux?
