Constructs new piecewise constant distribution object.

1) Constructs a distribution object with n = 1, ρ0 = 1, b0 = 0, and b1 = 1.

2) Constructs a distribution object from iterators over the interval sequence [first_i, last_i) and a matching weight sequence starting at first_w.

3) Constructs a distribution object where the intervals are taken from the initializer list ilist_i and the weights generated by the function fw.

4) Constructs a distribution object with the nw intervals distributed uniformly over [xmin, xmax] and the weights generated by the function fw.

5) Constructs a distribution object initialized with the parameters param.

Parameters

first_i	-	iterator initialized to the start of the interval sequence
last_i	-	iterator initialized to one-past-the-end of the interval sequence
first_w	-	iterator initialized to the start of the density (weight) sequence
ilist_i	-	initializer_list yielding the interval sequence
fw	-	double(double) function yielding the densities
nw	-	the number of densities
xmin	-	the lower bound of the interval sequence
xmax	-	the upper bound of the interval sequence
param	-	the distribution parameter set
