Added offline support

[han-steve]

Finally added offline support. Run the server by yarn server. You need an extension to block CORS in chrome (is there any way to avoid this? Can I just have the tiles be served in localhost instead of another server?). Since the tiles downloaded are mostly at 15x zoom, zooming out and moving around on the map can cause them to disappear. But it should serve the purpose for now.

@SteveHan-233 can you fix conflicts

There's only one conflict left. Can you copy the values for the coordinates into your config file?

Hey @SteveHan-233,

• Can you explain the difference between tiles/ and Server/?
• Move the mapbox-gl.css and js to some where else other than the root directory (just somewhere more specific to how it's used)
• Can you add any test files and map pngs to the .gitignore (You will need to delete them, commit, add to gitignore, commit)

Sorry for the late reply. 1. tiles/ was excessive and I deleted it. 2. I moved them to public/ 3. I'm not sure what you mean. Why do you want to put the pictures in git ignore? Don't I have to push it onto GitHub for you to access them?

We should be able to just run the script and generate them. This way we don't bloat the repo's filesize and we can just generate images for a location when we need them (e.g. before flight tests that are not at the same location).

The way I got the images was by opening up chrome, checking the network tab to see the tiles requested from the server, copying and pasting their links into a text file, and then having the python script read the links and download the images. I don't think I can automate this process.

Darn, in that case just zip the images you have and store them somewhere else for now. Then add maybe a "OFFLINE.md" readme that details how you got the images.

I'd recommend writing the files to some predictable directory outside the repo. Then you don't have to worry about them being committed
