@tongtybj I think we should merge these commits to master for new quadrotor users. I resolved conflits and fixed a little in this branch. Can you condsider merging? or are there any tasks remained?

Thank you for your reminder. I will refactor all commits before merging, since there are some unnecessary conflicts with master branch.

@tongtybj config file in hydrus package is used here. So I think mini_quadrotor package should depend on hydrus or place the same file in this package.
