Description: 
Adding Very Fast Reservoir Sampling 
(http://erikerlandson.github.io/blog/2015/11/20/very-fast-reservoir-sampling/)

An improved version of Reservoir Sampling, it's used to deal with small 
sampling in large dataset, where the size of dataset is much larger than the 
size of sampling.

It is a random sampling proved in the link. The average possibility is P(R/J), 
where R is size of sampling and J is index of streaming data 

Thanks Erik Erlandson who is the author of this algorithm help me with 
implementation.

(http://erikerlandson.github.io/blog/2015/11/20/very-fast-reservoir-sampling/)

An improvement version of Reservoir Sampling, it's used to deal with small 
sampling in large dataset, where the set of dataset is much larger than the 
size of sampling.

It is a random sampling proved in the link. The average possibility is P(R/J), 
where R is size of sampling and J is index of streaming data 

Thanks Erik Erlandson who is the author of this algorithm help me with
