Tidy up the file structure
At the moment, selecting the necessary data files is a mess of trying to find the right folders.
- The file and folder layout for where we find FASTAs and where we find things like AIC data and Kozak data, needs to be improved to make more sense.
- The file selectors should be independently defaulting to their respective folders we have made for their submodules. That means that when you use one file selector in the app for one thing, it should not change where the next file selector points to.
