/**
 * This class holds information about a routing profile.
 *
 * A routing profile specifies the type of vehicle that will go through the route
 * and the conditions with respect to the traversal of different types of edges
 *
 * For instance, a pedestrian can traverse streets in both directions, walk through
 * pedestrian ways and almost all types of ways except motorways, climb steps, and
 * can ignore turn restrictions, while a handicapped person would have the same profile
 * except for climbing steps. A car can drive at the maximum allowed speed of the way,
 * and can not use cycleways nor pedestrian ways, while a bicycle can, but its maximum
 * speed for any type of way would be around 50km/h.
 *
 * When combined with public transit data, information of which types of transport modes
 * are allowed for the vehicle can be stored in the profile. For instance, bicycles are
 * usually allowed to travel on board of trains, trams and subways.
