Parse SVG paths into matplotlib Path objects for plotting.

A path in SVG is defined by a 'path' element which contains a d="(path data)" attribute that contains moveto, line, curve (both cubic and quadratic Béziers), arc and closepath instructions. Matplotlib actually supports all of these instructions natively but doesn't provide a parser or fully compatible API.

Based on:

1. svg_parse for matplotlib by Nicolas P. Rougier (BSD license).
2. svg.path by Lennart Regebro (MIT license).

This module adds the path commands missing from (1), including smooth curves and endpoint-parameterized elliptical arcs.

>>> from svgpath2mpl import parse_path
>>> parse_path('M 100 100 L 300 100')
Path(array([[ 100.,  100.], [ 300.,  100.]]), array([1, 2], dtype=uint8))

There are likely still issues with implicit commands and subpaths to be sorted out.
