ArchAddOn

    Straightforward toolbox of field types, widgets, and validators for 
    Archetypes.

    Please feel free to add your own new fields, widgets, and validators
    here, if you think they are general-purpose. I intend for this to be
    not sample or learning archetypes add ons (ArchExample is for that),
    but real-world usable toolbox pieces.
    
    At this time, this requires the most recent CVS of Archetypes
    (since that uses a new model for custom widget view macros). This
    should become mainstream for Archetypes 1.3 branch and better.
    
    
Features

	* New Fields for:
      
      - USAddress
      
      - USPhoneNumber
      
      - Email
      
      - Link
      
      - Instruction (only shows description on edit form, for adding sectional
        help or other HTML markup to an edit form)

      - DynamicField. This is a textual field that can contain TALES
        expressions which are evaluated. So you can add a "body" field to
        a schema that is of this type, and have it be a mix of HTML content
        and TALES expressions (just like in a ZPT).

      - SimpleDataGridField. A lines field with embedded vertical bars for fields. If the
        columns property is set, the isValidGrid validator will ensure that
        the entered text has exactly that number of columns for each row.
        If strip_whitespace is True, the individual cells in the grid will
        be stripped of leading and trailing whitespace (that is, whitespace
        added around the delimiter).
        If column_names is set to a tuple or list of strings, it gives the names
        of columns in the grid. The getDataGridRow script and the getRow() method
        will return a dict using these column names as keys rather than using the
        column numbers (starting from zero).
        Fields are just strings, with no internal validation, etc.

    * Matching widgets for these types

    * Validators:

      - FormattedUSPhoneValidator: (999) 999-9999

      - USAddressValidator

      - isValidGrid
