Description:

Instances (and derived instances) are used temporarily while a view
is created from a spec. They collect attributes from a specArray and
know how to create & initialize a view from those.

They are not normally used by applications.

Notice: 
    this class was implemented using protocol information
    from alpha testers, literature and by reading public domain code
    - it may be incomplete or oncompatible to the corresponding ST-80 class. 
    If you encounter any incompatibilities, please forward a note 
    describing the incompatibility verbal (i.e. no code) to the ST/X team.

Usage example(s):

example from ClassChooser PD code:

        UISpecification from:
             #(#FullSpec 
                #window: 
                    #(#WindowSpec 
                        #label: 'Unlabeled Canvas' 
                        #min: #(#Point 50 50 ) 
                        #bounds: #(#Rectangle 448 407 648 607 ) ) 
                #component: 
                    #(#SpecCollection
                        #collection: 
                            #(
                                #(#LabelSpec 
                                    #layout: #(#Point 0 2 ) 
                                    #label: 'Classes:' )
                                #(#SequenceViewSpec 
                                    #layout: #(#LayoutFrame 0 0 27 0 0 1 0 1 ) 
                                    #model: #classChoice 
                                    #tabable: false ) 
                                #(#InputFieldSpec 
                                    #layout: #(#LayoutFrame 70 0 2 0 0 1 25 0 )   
                                    #model: #classPattern ) ) ) )

fromView: aView

create and return a new instance, by walking over a view's hierarchy.
(used by the UIPainters pick-a-view function)

fromView: aView callBack: aTwoArgCallBackBlock

create and return a new instance, by walking over a view's hierarchy.
(used by the UIPainters pick-a-view function).
For every created subSpec-element, the callBackBlock is evaluated,
passing the specElement and the view as arguments.
This can be used to fill in additional information, which cannot be
extracted from the view (for example: names, aspects etc.).
The callBack argument may be nil.

fromViewWithLayout: aView

label: l layout: ly

model: m label: l layout: ly

model: m label: l select: s layout: ly

model: m layout: ly

model: m menu: l layout: ly
