Addition of 'Edge Drawing' and 'Edge Drawing Parameter Free' algorithms to skimage?

[Robin Wilson]

Hi Egor,

The paper on the basic ED algorithm is available 
at https://www.researchgate.net/profile/Cuneyt_Akinlar/publication/257466884_Edge_Drawing_A_combined_real-time_edge_and_segment_detector/links/55daba4008ae9d659491f9c0.pdf

I can't find a freely available copy of the EDPF paper, but to be honest 
the descriptions on the websites I linked to are very similar to the paper 
content - exact copies in some cases!

I've actually had better performance than I was expecting, and even better 
performance when using numba for JIT compilation. I assume I'd get similar 
improvements with Cython.

Cheers,

Robin
