Shows first semester GPA during second semester

[Suhas-13]

Closes #70

Uses fetch API to get grade history page and display first semester GPA during second semester.

Can this be merged or do you want me to wait for #112 and use the classes from that instead?

[gary-kim]

I've actually just been waiting for a review for that PR. Would you like to try reviewing it?

EDIT: You know what, @insertcustomname, how would you rather do this? Should we just merge this one first? I can refactor to use the classes here as well in #112 so would you rather merge this one first?

[gary-kim]

Code itself looks good but you seem to have some .DS_Store files in the commit as well as a merge from master. Could you rebase your branch on top of current master and get rid of the .DS_Store files?
You're also welcome to put a copyright header in the file.
Thank you!

EDIT: Also, I'm worried about a race condition in which the request for the 1st semester grades finishes first and the semester 1 GPA is below the semester 2 GPA. You think we could move that to after the semester 2 GPA has been added to the page?

[gary-kim]

Just to prevent accidental merge. See above :)

I fixed the race condition, I tried adding the DS_store to the git ignore but not sure if it worked.

[gary-kim]

.DS_Store should probably be part of your global .gitignore but I'm okay with having it in the repo .gitignore if it means dealing with less Mac users accidentally committing the file. 😄
Also, you need to rebase your branch on top of the current master and remove the commits with dependency bumps. Actually, should I do it for you?

[Suhas-13]

Yeah that would be really helpful, thanks!

[gary-kim]

@insertcustomname What do you think?

[Suhas-13]

Great thanks, can we merge it?

[gary-kim]

LGTM

Thank you
