Changes in version 1.5.3 (2020-03-23)                  

  - Allow the user to decide whether to ordinate the null matrices
    independent on the ordination of the empirical interaction matrix.
    Gives a bit more flexibility.

                 Changes in version 1.5.2 (2019-10-13)                  

  - Order the null matrices for Coherence, and allow option to order
    them for turnover calculation. Not ordering nulls for Coherence
    results in erroneous positive coherence.

                 Changes in version 1.5.1 (2018-08-17)                  

  - Do not ordinate the null matrices. This won't affect the results
    from fixed-fixed null.

                 Changes in version 1.5.0 (2018-01-20)                  

  - Implemented the original null model for turnover as outlined in
    Leibold and Mikkelson 2002. Previous versions used a more
    traditional null model approach than shifting species filled ranges
    across sites as a block. There are pros and cons to both methods,
    but now the user has a choice.
