  - Added a suite of tools for operating on preferences.
  - Added two summary functions for preferences:
    1.  instant-runoff voting algorithm
    2.  covariance matrix based on rankings matrix representation
  - Improved preflib interface to fail gracefully, which is why
    prefio 0.1.1 was taken down from CRAN.

    C] rather than "A > B > C").
  - Fixed a bug when loading preferences from orderings format.
  - Allows an empty preferences object (displays preferences(0)).
  - Allow blank preferences (displays [blank]).
