cpp/numeric/random/piecewise linear distribution/piecewise linear distribution

Constructs new piecewise linear 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 and a matching weight sequence starting at.

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

@4@ Constructs a distribution object with the intervals distributed uniformly over.

@5@ Constructs a distribution object initialized with the parameters.
