graph.subject('air').isDependencyOf('human');
=> true

// I need to know if human has a dependency to the air
graph.subject('human').hasDependencyTo('air');

// What nodes are referencing 'air' as a dependency?
graph.subject('air').references
=> ['human']

// What nodes are dependencies of 'human'?
graph.subject('human').dependencies
=> ['air']
