需要实现如下目标：
1. 需求管理, 子需求管理（一个需求可能拆分成若干个细的需求）
2. Bug管理
3. 需求/子需求和Bug相关联，可以看到每个需求相关的Bug数量及进度(Redmine支持 task > subtask > subtask 模式)
4. 可以根据条件进行搜索，比如说想看有多少Open的Bug, 每个开发人员Fix bug的进度等
Step1: install redmine
根据教程安装： http://blog.csdn.net/benkaoya/article/details/8762935
Step2: login as admin
默认的管理员用户名是 user/123456?? 不太记得了
Step3: create project
Step4: create requirement(New feature)
Step5: creat sub-requirement(Sub-task related to New featrue)
Step6: create bug(Sub-task related to sub-requirement)
Step7: check project progress in Gantt(need choose due date in task/sub-task)
