Great work!! I've verified 'mvn clean install'.

> The core feature of cost-based optimizer is cost-based join enumeration
> approach. The main objective of this is to find the best join order from lots
> of enumerated join trees. In database community, there have been many studies
> for join enumeration ways.
> It would like to great to provide a generic and pluggable interface for join
> enumeration algorithms. It may encourage contributors to implement various
> join enumeration ways, and users could choose the best join ordering
> algorithm for their purpose.
