Align equal signs

Dear all,

I want my code to align equal signs of subsequent lines, e.g.

```
a = b;
longerVariable = c;
```

Is this functionality available?

Best

No files, tests, or entry points are named in the issue. Start by locating the MATLAB formatting and configuration entry points, then define how alignment should work for subsequent assignments and what test or formatted-output example demonstrates that the feature is complete.
