# MenuEntry message.

# Each InteractiveMarker message has an array of MenuEntry messages.

# an ID number and a \"parent_id\" field.  Top-level entries are the
# ones with parent_id = 0.  Menu entries are ordered within their
# level the same way they are ordered in the containing array.  Parent
# entries must appear before their children.

# Example:
# - id = 3
#   parent_id = 0
#   title = \"fun\"
# - id = 2
#   parent_id = 0
#   title = \"robot\"
# - id = 4
#   parent_id = 2
#   title = \"pr2\"
# - id = 5
#   parent_id = 2
#   title = \"turtle\"
#
# Gives a menu tree like this:
