Macro russell_chk::assert_vec_approx_eq

macro_rules! assert_vec_approx_eq {
    ($a : expr, $b : expr, $tol : expr) => { ... };
}

Asserts that two vectors have the same length and approximately equal values.

On panic, this macro will print the values of the expressions with their debug representations.

A tolerance must be given for the absolute comparison of float-point numbers.
