jensen-shannon computations to compute wrong values when 0 values were present in the input vectors (see issue #4 ; Many thanks to @wkc1986)jensen-difference computations to compute wrong values when 0 values were present in the input vectorsJSD() gives NaN when any probability is 0 - see https://github.com/HajkD/philentropy/issues/1 (Thanks to William Kurtis Chang)dist.diversity() and distance() when check for colSums(x) > 1.001 was peformed (leak was found with rhub::check_with_valgrind())Initial submission version.
