Format the output

Sometimes your standard out is a little hard to read. Take this multilevel hash and make it human readable.

Input

{Vertex('x'): {Vertex('v'): Edge(Vertex('v'), Vertex('x')), Vertex('z'): Edge(Vertex('z'), Vertex('x')), Vertex('y'): Edge(Vertex('y'), Vertex('x'))}, Vertex('y'): {Vertex('x'): Edge(Vertex('y'), Vertex('x')), Vertex('w'): Edge(Vertex('w'), Vertex('y')), Vertex('z'): Edge(Vertex('z'), Vertex('y'))}, Vertex('z'): {Vertex('x'): Edge(Vertex('z'), Vertex('x')), Vertex('y'): Edge(Vertex('z'), Vertex('y')), Vertex('u'): Edge(Vertex('u'), Vertex('z'))}, Vertex('u'): {Vertex('v'): Edge(Vertex('v'), Vertex('u')), Vertex('w'): Edge(Vertex('w'), Vertex('u')), Vertex('z'): Edge(Vertex('u'), Vertex('z'))}, Vertex('v'): {Vertex('u'): Edge(Vertex('v'), Vertex('u')), Vertex('x'): Edge(Vertex('v'), Vertex('x')), Vertex('w'): Edge(Vertex('w'), Vertex('v'))}, Vertex('w'): {Vertex('u'): Edge(Vertex('w'), Vertex('u')), Vertex('v'): Edge(Vertex('w'), Vertex('v')), Vertex('y'): Edge(Vertex('w'), Vertex('y'))}}
