    a view for editable text which can evaluate expressions.

    I.e. its basically a view for editable text, with added

    'doIt', 'printIt' and 'inspectIt' functions on the popup-menu.

    The action to be performed on doIt is defined by a block,

    which can be defined by the owner of this view.

    (thus you can put a workspace into more complex widgets, and

     control what should happen on 'doIt').

    A useful default action is automatically defined, which simply 

    evaluates the selection as a smalltalk expression. 

    (but, a lisp or prolog workspace would define its own action,

     to call for another compiler/interpreter  ...)

    Caveat:

        in this version, Workspace does not yet support doIt in MVC setups.

        For now, simulate this by setting the doItAction, to notify the

        model manually about the doIt.

    [instance variables:]

      doItAction      <Block>         block to evaluate for doIt

      errorFgColor    <Color>         fg-Color to be used when highlighting errors 

      errorBgColor    <Color>         bg-Color to be used when highlighting errors

      codeStartPosition               private temporary

    [styleSheet values:]

      codeErrorSelectionForegroundColor     fg color to highlight errors

                                            (default: selection fg)

      codeErrorSelectionBackgroundColor     bg color to highlight errors

                                            (default: selection bg)
