Sebastian Kuzminsky 2da39e4c02 Arc line intersect, take 2 (#60)
* add Line.point_to_t() and tests

* add Arc.point_to_t() and tests

* add a bunch of failing arc/line intersection tests

This commit contains a bunch of failing arc/line intersections that I
and other people have run into.

All these tests are fixed in the following commit.

* better implementation of Arc.intersect(Line)

Fixes mathandy/svgpathtools#35.

This commit fixes all the arc/line intersection test cases added in the
previous commit.

This implementation provides special handling in Arc.intersect() when
`self` is a non-rotated Arc and `other_seg` is a Line.  In this case
it uses the straight-forward closed-form solution to identify the
intersection points.

Rotated Arcs and Arcs intersecting with non-Line objects still use
the pre-existing intersection code, that part is totally untouched by
this commit.

Michael X. Grey 360d6b224c Flattening SVG groups and handling transforms (#55)
* Some progress (and added CONTRIBUTING.md)

* fixed documentation line-width to be PEP 8 compliant

* fixed documentation line-width to be PEP 8 compliant

* style changes

* made some design changes

* Make the Document class available when importing the library

* Add a method to parse transform strings

* Iterate on the implementation of the Document class

* Tweaks to transform parsing implementation

* Implementing a depth-first flattening of groups

* Fix multiplication of numpy matrices -- need to use .dot() instead of operator*

* Create a unit test for parsing SVG groups

* Return a reference to an element instead of a copied dictionary of attributes

* Add a test for <path> elements that contain a 'transform' attribute

* Fix the use of some numpy operations

* Remove untested functions

* Fix add_group() and write tests for adding groups and paths

* Update documentation of document module
