graph created successfully!
graph info: 
  your graph is empty...
creating some vertices in our graph...
graph info: 
  vertex 0x2020010 of type INPUT
  vertex 0x2020014 of type INPUT
  vertex 0x2020018 of type BUS
  vertex 0x202001c of type BUS
  vertex 0x2020020 of type OUTPUT
graph info: 
  vertex 0x2020010 of type INPUT
  vertex 0x2020014 of type INPUT
  vertex 0x2020018 of type BUS
  vertex 0x202001c of type BUS
  vertex 0x2020020 of type OUTPUT
connecting some vertices together
  connecting 0x2020010 to 0x2020014
  connecting 0x2020014 to 0x2020018

So we would end having this kind of graph:
 
A+--------->B+-------->C    (No cycles)


Cycled Denied!
0x2020014 to 0x2020018
graph info: 
  vertex 0x2020010 of type INPUT
  vertex 0x2020014 of type INPUT
  vertex 0x2020018 of type BUS
  vertex 0x202001c of type BUS
  vertex 0x2020020 of type OUTPUT
  we have an edge from a INPUT 0x2020010 to INPUT 0x2020014
destroying graph now.
