Changes in version 0.2.0 (2016-08-27)                  

  - dfun in edfun now accepts NULL - and will return NULL in such a
    case. This is useful if using the functions ONLY for creating the
    CDF and inv-CDF and wanting to save computation time.
  - a few fixes before going on CRAN.

                        Changes in version 0.1.0                        

  - First version. The core functionality of edfun works.
