}

A macro for defining a custom graph with a specific set of constraints.

The resulting graph is generic over vertices and weights (<V,W>) and implement GraphWrapper and the constraints given.

Syntax:

struct <graph name>
where <name of type implementing ConstrainedGraph>
impl (<constraint>),*
use (<GraphWrapper to use to uphold the constraint, i.e. will wrap the ConstrainedGraph>),*

The 'impl' and 'use' clauses are optional.
