EDIT: `get_weight` is reading the correct weight

[hdavid16]

Since the weight matrix is actually the transpose of the weight matrix (sbromberger/SimpleWeightedGraphs.jl#65 (comment)), the wrong value is being read in the current implementation:

julia> s = SimpleWeightedDiGraph([1,2,1], [2,1,2], [1,1,1])
{2, 2} directed simple Int64 graph with Int64 weights     

julia> get_weight(s,1,2)
2

Which is wrong because the weight of the Edge 1 => 2 is 1, not 2. This occurs because, get_weight is calling s.weights[2,1]. However, the weights field is not transposed.

Nevermind, the issue is because of the way the graph is being generated (which is warned against in the Readme). The current implementation is correct.
