* 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
