Changes in version 1.0.1 (July 3 2018)

 Removed default values for arguments id, event, start, stop, and expos of the WCE and checkWCE functions. 

 Fixed a potential bug in the estimation of the WCE model resulting from the values passed to arguments id, event, start, stop, expos and covariates of the WCE function.

 Removed the option to specify the location of interior knots (with argument int.knots).

 Changed names of some attributes of WCE objects to increase clarity:
   - PL changed to loglik
   - a changed to aic
   - ne changed to nevents
