Implement decorators

[greg-d128]

Partial implementation completed. Eventually I might have multiple different types of decorators depending on features desired.

Decorators will allow for more control as they can perform management before the function is called (although that should be kept to minimum).

Desired functionality:

• Catch exceptions and rewrite code.
• Persist code (may not be in source code - Database with older versions of code still available may be better).
• Decorators should allow to pass in a dict object? with parameters to help guide the prompt. Functionality of the code, etc.
• Decorators should automatically handle passing functions as parameters.

Future functionality:

• Decorators could retrieve and try multiple past versions of a function.
• Could perform unit testing on the newly created function before accepting it. (perhaps adding a new use case to the unit tests for future?)
• Could perform A/B testing, to handle the case where only small percentage of requests is failing. All failures would be handled by new code, but only small number of working requests should be handled by new satisfied that all looks good.
• Use LLM to make sure that the output of a function is following guidelines. Probably by writing a function to validate the output so it is faster.

This is a little bit easier, as I'm not working with a stack, but live program state.

I've got first decorator with function rewriting. A small proof of concept for automatically generating unit tests was successful.

Some progress on decorators. Decorators will be the future I think.

There will be several kinds. Currently ExceptionHandler has partial implementation.

• ExceptionHandler - similar to Necromancer, except it catches the code much closer to the source. It is able to intercept the exception and re-run the function. It will also have access to a better description of what this section of code is meant to do.
• LogVerifier - New. Since I am now including logging module, can I use it to obtain logs from this section of the code and use it to create a better version of the code when something goes wrong?
• AssertVerifier - Respond to assertions.

Also, optionally, the decorators could run the new code through unit tests before putting it into production.

Should the ai control the unit tests?
