........
  r7616 | ryanmay | 2009-08-31 12:27:12 -0500 (Mon, 31 Aug 2009) | 1 line
  
  Update barb_demo.py with an example using masked arrays.
........
  r7617 | ryanmay | 2009-08-31 12:29:41 -0500 (Mon, 31 Aug 2009) | 1 line
  
  Pull _parse_args out of Quiver and Barbs classes, as we have multiple, diverging copies of the same code.  Now the shared code will actually be shared.
........
  r7618 | ryanmay | 2009-08-31 12:34:50 -0500 (Mon, 31 Aug 2009) | 1 line
  
  Use atleast_1d instead of asanyarray.  This allows passing in scalars to quiver/barbs.
