(But no changes for 0.4.7)
Version 0.4-6 2013/10/30
Added function dasytriangular for the density of asymmetric triangular \ 
distribution as described in Mardia (1972)
In this version two functions are available for evaluating the median \ 
(medianCircular which allows for the dispersion para
meter and median.circular with only the median reported), however medianCircular \ 
is deprecated and it will be removed in t
he next releases.
Added mean.circular.c to calculate the circular mean in C language.
New algorithm for circular median. The implementation is in C language.
Added function for Hodges Lehmann estimate of the median for circular and non \ 
circular data.
Several bugs fixed.
