 Version 0.0.2: name changed to spOSMroute, since on there had been another
                OSMroute already.
 =============================================================================
+(2013-07-23):
+- added map_way_append_to_hash and map_area_append_to_hash to speedup 
+  map_hash_realloc, which took most almost 30% of all time.
+
 (2013-07-19):
 - speeding up converting process.
