Function Path.Reset

All inheriting path types (e.g ConstantPath, RandomPath, etc.) which declare their own variables need to override this function, resetting ALL their variables to enable pooling of paths. If this is not done, trying to use that path type for pooling could result in weird behaviour. The best way is to reset to default values the variables declared in the extended path type and then call the base function in inheriting types with base.Reset().
