Parameters
----------
keys : list
A list of edge keys (as uv pairs) identifying which edges to draw.
Default is to draw all edges.
Notes
-----
All edges are named using the following template:
``"{}.edge.{}-{}".fromat(self.mesh.attributes['name'], u, v)``.
Examples
--------
>>> mesh_draw_edges(mesh)
>>> mesh_draw_edges(mesh, keys=mesh.edges_on_boundary())
