<h2>Adding Some Color to your Graph</h2>
<p>BGL attempts to be as flexible as possible in terms of accommodating how
properties are attached to a graph. For instance, a property such as edge weight
may need to be used throughout a graph object's lifespan and therefore it would
be convenient to have the graph object also manage the property storage. On the
other hand, a property like vertex color may only be needed for the duration of
a single algorithm, and it would be better to have the property st
