## Problem
In some IFs, the metadata like `title` ,`citation`, etc are still in outside metadata inner class. It would be neat and have better structure if we put it under one class.
## Solution

Hi there,
great work. This interface really improves the handling of numpy.optimize.
The issue:
When passing method="nelder" to minimize, a leastsquare fit is performed.
This is due to the code fragm…
