 * First set `local` to `false` and `range` to encompass all sane values for example `[0.5, 0.5, 0.5, 3.2, 3.2, 3.2, 0.1]` will explore all rotations, plus all translations within 0.5m. The result of this optimization will get you in the ballpark but will most likely have significant error.
 * Secondly take the solution from above and use this to set the `inital_guess`, then rerun with `local` set to true and a smaller range for example `[0.1, 0.1, 0.1, 0.5, 0.5, 0.5, 0.01]`.
