    The ResourceSelectionBrowser allows you to browse in class hierarchies

    and to select resource methods for loading or to saving resource 

    specifications (#canvas, #menu, etc.).

    [instance variables:]

        resourceMethod          <Symbol>        selector of the resource spec

        resourceClass           <Symbol>        class of the resource spec

        resourceSuperclass      <Symbol>        root class of the tree list

        resourceTypes           <Array>         allowed resource types

        allClasses              <Array>         list of the subclasses of resourceSuperclass

        classSelectionBlock     <Block>         by evaluating this block the class selection is done
