# changelog:
# *** Based on Trekking profile, added flag driven customizations
# Hiking Version 1.6 ALFA
# 2014-10-10 (c) Poutnik
# Route_foot related hints were improved with usage of Hiking.brf from below and by Arndt comment
# http://pastebin.com/YLpkGVD4
# http://forum.openstreetmap.org/viewtopic.php?pid=447507#p447507
#
# 2014-10-10 v1.1 - changed hiking route preference logic
# 1.2 - fixed preference counting bug
# 2014-10-11 1.3 - adding foot route to hiking routes,
# fixed ferry cost to respect initial cost triggerring.
# added bikeaccess, added shortest way mode, code cleanup
# 2014-10-12: v1.4 - involving turncosts and way/node initial costs as orientation/decision penalties,
# but turning them off for sticking to hiking routes as extra preference,
# tweaking cost preferences
# 2014-10-13 v1.5
# redesigned route preference policy - turncost turned off even for nonsticky but preferred hiking routes
# cost tweaking.
# removed uniform cost=1 for sticky hiking routes, to distinguish quality
# giving penalty 1 for non hiking routes at sticky hiking routes.
# used not round costs to often trigger initial cost calculation
#v1.51 - bugfix of redundant routing penalty
#v 1.6 - initialcost penalty only for sticking routes, decreased way penalties for preferring routes
# 31/5/2015 v 1.7 ALFA - sac_scale + sac_scale_limit implemented
# 10/6/2015 v1.7.1 ALFA - sac_scale improved, MTB scale integrated to SAC scale
# sac_scale_preferred implemented, with progressive penalizing for SAC <> SAC preferred
# 10/6/2015 v1.7.2 BETA - Fixed general way access penalties
