New front end implementation using the Python VM and JEP

[juliandolby]

Given that Jython seems to be dead, we have been working on a new Python front end for WALA based on the standard Python runtime accessed via Jep. It is not entirely done, but enough works that I would like to have it integrated into WALA. I have put my needed changes to WALA itself into a branch called jumpstart-jep-merge and the new front end exists at github.com:juliandolby/jumpstart2024/com.ibm.wala.cast.python.cpython.

I have made many of the existing tests work for the new front end, and added a few more. The main headache is building Jep in a Python env and making the WALA front end use it. I have this working here, and it would be great to help someone outside get set up with it.

Hi @juliandolby the jumpstart-jep-merge branch is on this repo, not the main WALA repo. So is the idea that the new Python frontend builds on the wala/ML code but requires no changes to core WALA?

Re-opening, as I think that this is ongoing (please correct me if I'm mistaken).
