An error caused by attempting to fulfil a dependency that was circular
@note This exception will be thrown iff a {Vertex} is added to a
{DependencyGraph} that has a {DependencyGraph::Vertex#path_to?} an existing {DependencyGraph::Vertex}
Initializes a new error with the given circular vertices. @param [Array<DependencyGraph::Vertex>] vertices the vertices in the dependency
that caused the error
