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

`bl`

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`

.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 |
