# Generic set of parameters required by any MBF-based navigation framework
# To use:
#
#  from mbf_abstract_nav import add_mbf_abstract_nav_params
#  gen = ParameterGenerator()
#  add_mbf_abstract_nav_params(gen)
#  ...
# WARN: parameters added here must be copied on the specific MBF implementation reconfigure callback, e.g. in:
#       https://github.com/magazino/move_base_flex/blob/master/mbf_costmap_nav/src/mbf_costmap_nav/costmap_navigation_server.cpp#L130
# Also, you need to touch https://github.com/magazino/move_base_flex/blob/master/mbf_costmap_nav/cfg/MoveBaseFlex.cfg
# when recompiling to ensure configuration code is regenerated with the new parameters
 
# need this only for dataype declarations
