Hi all, I'm Chen and I'm new to commons-collections. I like commons-collections cause it provides many useful data structures. I'd like to contribute to it.
Last month I pushed several PRs in github : https://github.com/apache/commons-collections/pull/114 https://github.com/apache/commons-collections/pull/115 https://github.com/apache/commons-collections/pull/117 https://github.com/apache/commons-collections/pull/118 I hope someone can review these PRs and give me some advices if time permits, therefore I can make it better. :) Thank you very much. Best regards, Chen
