Since openslam_gmapping has been directly adopted, we can keep the original formatting of the code. This also applies for all the other openslam_gmapping files that have been changed

Hi @shiveshkhaitan. I agree. I have reverted this to adopt the original code.

This line has been moved below. The change does not make any difference. We can keep the original declaration

Thanks for the addition of parameters. But this can be added as a separate PR since it is unrelated

Thank you for the modifications @skylerpan. Some of the parameter related changes are still not reverted. Can you please revert them as well. Please feel free to have them as a separate PR.

Hi @shiveshkhaitan. I reverted all the code excepting two bug fixes, and also rebased the commits. Many thanks.
This implementation uses message filter to sub topic. But message filter default only passes topic with reliable qos. I modified the qos setting in message filter to pass both reliable and best-effort topic.

Original implementation uses message_filters to subscribe to the scan topic.
But message_filters default only passes topic with reliable QoS.
I modified the QoS setting in message_filters to pass both reliable and best-effort topics.
And I have merged some modifications from @bergercookie's fork.
