Now that we are able to open and close a window, we are going to need some controls (views) to fill it up.  Part of the following has been previously published, but new controls have been added.  Some controls work right out of the box; others will need to be hooked up later. Note that the NSStepper (little arrow) is connected to the display field without using a controller by using reciprocating Target/Action.  It may also be used with a controller.   If you want to see an image in the NSImageView, select one of your own .png images and put it in the folder with this demo.  You will have to name it "myImage.png" or else change the name in the demo (two places).  Un-REM the "include resources xxxx.png" line.  Please note the many bezel styles for NSButton.  Also note that the "grid" that they are printed in is unbalanced, ie it is not rectangular.  There supposedly is more overhead with this arrangement than with NSMatrix, but the latter only does rectangular configurations and so far I have not found a way to construct it by column; it prefers construction by row.  The main point that I would like to make is that many controls may be created using this common template.  Once the control has been created, it must then be added as a subview of the window's contentView and may then be released.
