Meta: added file 'git_conventions.md' to provide git commit message conventions for everyone.

git_conventions.md

+# GIT CONVENTIONS
+
+## FOREWORD
+(Do not edit this foreword)
+
+I have been viewing our past commit messages recently and while it does explain
+the changes we made, it can be greatly improved through standardizing our GIT
+messages. I'm creating this MarkDownfile (.md) to list down all the conventions
+I found on the internet and modified for this project. I'm hoping that all of
+us will follow these conventions. This is not just for me, this is for all of
+us.
+
+If you feel you can add more to this file, go ahead. The conventions I listed
+here are by no means comprehensive or complete, but what I think is sufficient
+enough for us as of writing this file (04/02/2022). Just make sure that there
+will be cases where the new conventions you added will be needed.
+
+Thanks! ~ Ray

+## GIT CONVENTIONS (AS OF 04/02/2022)
+Git messages should be as follows:
+> SUBJECT: A summary of what you did
+
+An example. <i> New Feature: added a new database named 'ID' in homepage. </i>
+
+As much as possible, your git messages should follow these guidelines.
+- Your git messages should be two or three sentences at most. Two is best.
+- Each sentence should communicate intent, explicitly, and <b>not vague</b>.
+
+<b> Types of Subject </b>
+- Fix: if you fixed a bug in the project. 
+- Style: if you're changes you make has an impact on the GUI. 
+- Improvement: if you made an improvements on pre-existing feature
+- Clean: if you cleaned messy code by reformatting, restructuring, changing
+variable, function, or class names, etc.
+- Meta: if you have modified the README.md file or added new files that are
+not part of the project itself but provides information to programmers on how 
+to write the program
+- Others: if it doesn't fit in with the any of the above. AS MUCH AS POSSIBLE
+AVOID THIS. 
+
+<b> Other Guidelines </b>
+- One commit message can have multiple subjects. For example, "New Feature: 
+added foo. Clean: reformatted views.py of homepage." However, the next subject 
+must be in a newline.
