Refactoring

As discussed in previous sprints, it is new to all of our members to use expoGO, typescript, and other various technology for the first time. Therefore, we didn't do much sorting of the files, instead just cramped everything into one single file. This isn't versatile and modular, therefore we took some time and break apart the single file and broke it into smaller pieces.

This has since made editing and adding related code much easier for us, and different members can work individually without having to wait another member's commit conflict etc.
