currently I am renaming functions to as before[as made by leosartaj] and creating tests for them. Any suggestions? @leosartaj @sumitsahrawat

Don't add [WIP] to the commits. Just the title of the PR.

Any replacement to this line @leosartaj ? I used this line to import exce and func_json

[leosartaj]

Yes. Try this

from rollcall import exce, func_json

You should not play with path.

[leosartaj]

If you already have a function say full_path_to that does the job. Use it.

Since we are not using json now, do I still use them? They are mixed up with json @leosartaj

[leosartaj]

subLIst is a list?

Please do not push any commits. I have not reviewed yet. Let @sumitsahrawat also pitch in.
Also for reviewing purposes and better understanding, I am opening an issue regarding using sql. It would be nice if you could describe the database structure there.
