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 and 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 fw intervals distributed uniformly over [xmin, xmax]
5) Constructs a distribution object initialized with the parameters param.

[edit] 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 sequnce
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
parm - the distribution parameter set
