A handy library for measuring the execution time of function.

[dependencies]
calculagraph = "0.1"
```rust
use std::{thread, time};
use calculagraph::timer_println;
fn main() {
thread::sleep(time::Duration::from_millis(10));
println!("job done");
}
``
The above example will printfn:main cost 10ms` at the end, You can also use the second
argument to define the format string you need.
