// These concept checks verify that the BGL classes implement the
// complete interfaces defined in the graph concepts. The concept
// checks are also useful for verifying whether user-defined graph
// classes satisfy the desired graph concepts. Note that these concept
// checks by themselves do not verify whether the classes model the
// concepts, for there are run-time requirements that are not checked
// here.
