Resource that creates a new span as the child of the span specified by the given kernel,
which typically arrives via request headers. By this mechanism we can continue a trace that
began in another system. If the required headers are not present in kernel an exception will
be raised in F.

Resource that attempts to creates a new span as with continue, but falls back to a new root
span as with root if the kernel does not contain the required headers. In other words, we
continue the existing span if we can, otherwise we start a new one.
