Constructs new piecewise constant distribution object.
1) Constructs a piecewise_constant_distribution object with n = 1, ρ0 = 1, b0 = 0, and b1 = 1.
2) Constructs a piecewise_constant_distribution object from iterators over the and interval sequnce 
[firstB, lastB) and a matching weight sequence starting at firstW.
3) Constructs a piecewise_constant_distribution object where the intervals are taken from the iitializer list 
bl and the weights generated by the function bl.
4) Constructs a piecewise_constant_distribution object with the 
nw intervals distributed uniformly over [xmin, xmax]
5) Constructs a piecewise_constant_distribution object initialized with the parameters 
param.[edit] Parameters
| firstB | - | iterator initialized to the start of the interval sequence | 
| lastB | - | iterator initialized to one-past-the-end of the interval sequence | 
| firstW | - | interator initialized to the start of the density (wieght) sequence | 
| bl | - | 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 |
