Comment (by aric):

 I moved the arpack wrappers from the sandbox to splinalg.eigen
 and updated the arpack.py wrapper, docstrings, and tests

 Tickets #366 and #554 can be closed with these updates.

 The issue of the wrong number of eigenvalues and eigenvectors in
 this ticket was a little more subtle than applying the patch above but I
 believe I have that fixed correctly.  See lines  248 and following in

 Ticket #418 (add shift modes) is not addressed in these changes.
 The addition of more solvler modes (shift and generalized
 eigenproblems) is yet to be done.

 There is still no high-level interface to arpack or other
 eigensolvers.  The proposal is for splinalg.eigen.speigs.
