Rob Nadal aeb9e85726 Added Subpaths to bezier-rs (#730)
* Added Subpath constructor, iterator and length

* Asserted that subpaths of len < 2 cannot be closed. Added len() and comments

* Added subpath to_svg(), made structs public, made quadratic use either in_handle or out_handle

* add bezier handles

* Added basic interactivity and index traits

* Added SubPath interactivity

* Added svg styling

* Broke subpath impl across multiple files. More sylistic changes per review

* Fixed format error

* Added closed subpath to documentation page

* Modified subpath to_svg to use functional style

* Stylistic changes per review

* Fixed build errors

* More sylistic changes per review

* Moved svg commands to constants

* Moved formatting for svg arguments to ToSVGOptions

* Renamed files in git

* Even more stylistic changes per review
