std::cauchy_distribution::cauchy_distribution

STD：Cauchy[医]分发：：Cauchy[医]分布

explicit cauchy_distribution( RealType a = 0.0, RealType b = 1.0 (1)(since C++11)
explicit cauchy_distribution( const param_type& params (2)(since C++11)

构造一个新的分发对象。第一个版本使用a和b作为分发参数，第二个版本使用params作为分布参数。

参数

a-the a distribution parameter (location)
b-the b distribution parameter (scale)
params-the distribution parameter set
