[Sanil14]

Overview:
Make a logs page that will display all actions including: role assign, role unassign, member info changes, member creations, member deletions, job deletion.

Frontend:
The page will show who did the action, what action they did, to whom they did the action to, and when they did the action.

Backend:
Database will have new table for logs and will add new row everytime a new action is done.

How to do it:
Separate file that will be "include"d in every required file, and a function will be called to log an action.
