Description:

a view for text which is known to be smalltalk code. 
It adds 'explain' to the menu, and defines another action: 
  explainAction to be performed for explain.

This action is to be defined by the user of this view 
(i.e. usually the owning browser)

In addition, uncomment/comment are added to the controlMenu.
These are smalltalk specific - if you plan to edit other language code,
you need a different kind of CodeView for that.

If used with a model, accept sends the changeMsg to it (as defined in EditTextView).
(however, it is possible to define both changeMsg and acceptAction)

See how doIt/printIt/inspectIt are handled in the superclass: Workspace.

Caveat:
    in this version, CodeView does not yet support MVC setups for doIt
    and explain.
    If required, simulate this by setting the doItAction and
    explainAction, to notify the model manually about whats going on.

[instance variables:]
    commentStrings          <Array>         an array with 2 entries;
                                            the first defining the EOL-comment string,
                                            the 2nd (another array) defining opening
                                            and closing comment strings.
                                            Default to ST/X comments,
                                            can be changed in an instance for other
                                            programming languages.

Instance protocol:

 explainAction: aBlock

set the action to be performed on explain

 formatAction: aBlock

set the action to be performed on format

 pointerOverWordAction: aBlock

 cursorReturn

 cursorReturn: withPossibleAutoindent

added an argument to disable autoindent, because this method is called from other
places as well (especially: the terminal emulator)...
