Add doxygen for all files

[SteveMacenski]

We have pretty good coverage on this already, but there are a couple of packages missing doxygen in the headers

[SteveMacenski]

A good first time issue user might want to just add these for a couple of header files missing them! You don't have to do everything at once, even a little bit at a time is super helpful

[SteveMacenski]

From a survey, these are the packages needed doxygen

• AMCL, sensors/laser/laser.hpp, amcl_node.hpp, angleutils.hpp, map/map_cspace.cpp remaining
• behavior tree
• costmap 2d: in order left is array_parser.hpp -> costmap_topic_collision_checker.hpp, costmap filters direcory
• navfn
• recoveries
• utils

@SteveMacenski this is my first time contributing to the project, I would like to take navfn first if possible.

[SteveMacenski]

That would be greatly helpful, thanks @mlsdpk!

[SteveMacenski]

I did utils and recoveries

Phew.... 2,000 lines later, finally complete!
