#### PaperColumn

PaperColumn objects are created by: Score_engraver

Standard settings:

`axes` (list):
  `'(0)`

  list of axis numbers. In the case of alignment grobs, this should contain only one number.

`before-line-breaking-callback` (procedure):
  `Paper_column::before_line_breaking`

  This procedure is called before line breaking, but after splitting breakable items at potential line breaks.

`X-extent-callback` (procedure):
  `Axis_group_interface::group_extent_callback`

  Procedure that calculates the extent of this object. If this value is set to `#f`, the object is empty in the X direction. The procedure takes a grob and axis argument, and returns a number-pair.

This object supports the following interfaces: item-interface, spaceable-grob-interface, axis-group-interface, paper-column-interface and grob-interface
