Inconsistencies when saving to a stretched image?

Hi, when the output image in SVG format is shaped to a stretched rectangle, there are inconsistencies in the way forms are reshaped. In the following example, the circle is...

`simplify_fractions` return `Float64` coefficients

``` julia using SymbolicUtils @syms x simplify_fractions(1/x + 1/(x^2 - x)) => 1 / (x - 1.0) simplify_fractions(1/x + 1/(x^2 - 2x)) => (x - 1.0) / (x^2 - 2x)...

degree of loops

I must feel stupid, but on every reference I encounter, a self-loop (undirected) counts for 2 in the degree of a node. This is the behavior on NetworkX (and I...

`random_configuration_model(3, [2, 0, 0])` never halt. This is because our implementation of the random configuration model does not allow self loops and multi-edges. In itself, it is already an oddity...

fixes #362 fixes the same bug in `kruskal_mst`

Fixes #363 In the tests, there was a loop encapsulating the `merge_vertices` tests, but these tests were not using the test graph, hence I moved it out and refactored it...

`merge_vertices` returns an undirected graph, even if the input is directed. The output graph should be the same type of graph as the input.

Switch to an adjacency list storage of vertices.

See [this conversation](https://discourse.julialang.org/t/performance-of-weighed-graphs/83661/4) This seems to be mostly equivalent to a sparse matrix (I mentioned slower access of weights, but using binary search, I think it should be same complexity...
