//! path exists to make paths much easier to write svg paths
//! while you can make the path anywey you like and send that as the argument, it may be
//! simpler to create it like below:
//!
//! ```
//! use mksvg::*;
//! let mut s = "".to_string();
//! {
//!     let mut svg = SvgFmt::new(&mut s);
//!     // ... normally do svg start
//!     svg.path(PathD::rel().m(5,5).l(10,10),Args::new().stroke("black"));
//!     // ... normally do svg end
//! }
//!
//! assert_eq!("<path d=\"m 5 5 l 10 10 \" style=\"stroke:black;\" />\n" 
//!             ,&s);
//!
//! ```
