* Topology.hh
*
* Description: The topology here is configurable; it can be a hierachical
* (default one) or a 2D torus or a 2D torus with half switches
* killed. I think all input port has a
* one-input-one-output switch connected just to control and
* bandwidth, since we don't control bandwidth on input ports.
* Basically, the class has a vector of nodes and edges. First
* 2*m_nodes elements in the node vector are input and output
* ports. Edges are represented in two vectors of src and dest
* nodes. All edges have latency.
