Initial TODO for LPython

[certik]

• Rename the lfortran binary to lpython
• Make --show-python-ast just --show-ast, the same with --show-asr, --show-cpp
• Merge a.py with lpython, probably using Cython
• Get --show-llvm working
• Get compiling to binaries working
• Remove all Fortran related files (parser, ast, ast -> asr, etc.)
• Rename namespaces from LFortran to LPython
• Add tests (run_tests.py for ASR mainly, and then integration_tests, we can simply call lpython on the main file and then run it, probably adapting cmake, so that we can use ctest to execute)

Hi @certik, Currently I'm figuring out a way to merge a.py with lpython.
I figured this much:

• The serialization output (which is present in a.py) must be fed as the input to the C++ function (Src -> AST or related).

How to do it?? Can you please brief out the implementation so that I can look around...

Should I work on this?

[Thirumalai-Shaktivel]

Yes, Of course. Add all the test files into the tests folder for now.
Regarding the extension, keep it *.py for now. Later, we can change as per our needs.
Also, Can you please include all the tests which you mentioned in the GitLab MR (lfortran: py branch)? [Like break, AugAssign, etc...]
