Changes in version 0.1.0                        

  - Initial CRAN submission.
  - Density, distribution function, characteristic function and random
    generation for the skew generalised normal distribution on the line
    (dsgn(), psgn(), cfsgn(), rsgn()).
  - Density, distribution function, quantile function and random
    generation for its wrapped version on the circle in the identified
    parameterisation (dwsgn(), pwsgn(), qwsgn(), rwsgn()), and its
    trigonometric moments (trig_moments()).
  - Estimation by minimum distance on the trigonometric moments with
    sandwich standard errors (fit_wsgn_trig()) and by maximum likelihood
    with parametric-bootstrap standard errors (fit_wsgn_mle()).
  - The characteristic function is evaluated through absolutely
    convergent integrals, so every routine is available for all shape
    parameters beta > 0.
  - The computation runs on a pure-C back-end shared with the Python
    package 'wsgnstat'.
