Circuits as Directed Acyclic Graphs


`DAGCircuit`	Quantum circuit as a directed acyclic graph.
`DAGNode`	Parent class for DAGOpNode, DAGInNode, and DAGOutNode.
`DAGOpNode`	Object to represent an Instruction at a node in the DAGCircuit.
`DAGInNode`	Object to represent an incoming wire node in the DAGCircuit.
`DAGOutNode`	Object to represent an outgoing wire node in the DAGCircuit.
`DAGDepNode`([type, op, name, qargs, cargs, ...])	Object to represent the information at a node in the DAGDependency().
`DAGDependency`()	Object to represent a quantum circuit as a Directed Acyclic Graph (DAG) via operation dependencies (i.e.
