## TODO:
1. Multiple functions in one graph.
	- Backend support
		- Integrals between functions (too hard to implement, maybe will shelve)
	- UI
		- Different colors (kinda)
2. Rerwite of function parsing code
	- Non `y=` functions.
3. Smart display of graph
	- Display of intersections between functions
4. re-add euler's number (well it works if you use capital e like `E^x`)
5. allow constants in min/max integral input (like pi or euler's number)
6. sliding values for functions (like a user-interactable slider that adjusts a variable in the function, like desmos)
7. Keybinds
8. nth derivative support (again)
9. Update function tests
10. rewrite FunctionEntry to move more information and handling to egui_app (such as config changes)
11. Threading
12. fix integral display
13. Improve loading indicator
14. Hash asset tarball and compare hash on runtime (just an idea, idk if this is actually worth it)
15. add comments in `parsing::process_func_str` for it to be better understandable
