linetype="curve" option not working

[juliohm]

using LightGraphs
using GraphPlot

G = DiGraph(2)
add_edge!(G, 1,2)
add_edge!(G, 2,1)

display(gplot(G, linetype="curve"))

LoadError: MethodError: convert has no method matching convert(::Type{Measures.Measure}, ::Float64)
This may have arisen from a call to the constructor Measures.Measure(...),
since type constructors fall back to convert methods.
Closest candidates are:
call{T}(::Type{T}, ::Any)
convert{T}(::Type{T}, !Matched::T)

This issue can be tracked down to this line in the source: https://github.com/afternone/GraphPlot.jl/blob/master/src/plot.jl#L191

@afternone , this is currently the main issue I have. I am trying to debug this algorithm for LightGraphs.jl and the labels of antiparallel edges are overwritten. Do you know why this error is occurring? I am assuming that with curved edges the labels won't be placed in the same location.

[afternone]

Curve line type is bit complicated. We can solve the overwritten problem in an easy way as shown in #4.

[juliohm]

@afternone I would say that curvy edges with labels halfway between nodes look much nicer than the solution in #4. :) Anyways, I can debug my algorithms now that you fixed that other issue, thank you! This package is being really helpful 👍

Finally fixed by #90
