The Definition in equations 2.32 & 2.33 from N.I. Fisher's 'Statistical Analysis of Circular Data', Cambridge Univ. Press 1993. is implemented.
Since version 0.4-4, the algorithm (not the definition) for the
calculation of the median is changed. For a measure of spread associated to the circular median use function meandeviation.
