Hello.

This is a duplicate of Ticket # 4497
After looking over the other tickets I wasn't sure anymore, if my patch
would belong there, so I decided to repost it here.
Please duely reprimand me if I violated any policies :)

https://code.ros.org/trac/ros-pkg/ticket/4497 reads:

//snip

For my project I needed the Costmap2DROS wrapper to listen to a different map topic than the hardcoded "map" one. I added an optional parameter (in(for) the configuration file) and found the change to be minimally invasive and quite useful. So I thought I'd share it.

The patch (against boxturtle r28817 but also applicable on cturtle ) is attached.

//unsnip

I attached the patch file to this message.

Hope you find this useful, too.

Best regards,
Andreas Tropschug
