Can get ids from all edited and deleted elements. Should be able to easily send data to back-end now. Waiting for back-end to be ready

Able to edit objects and draw more objects without things breaking. Ready to send edited objects to back-end once they're ready

Moved GeoJSON LayerGroup from back-end under FeatureGroup in DrawTools.js. Iterating through every layer, adding necessary options and adding to map.

Fix bugs with layers disappearing when adding new ones, still need to work on deleting layers already made

Fixed placeholder text not appearing when emptying textbox. Fixed marker going under textbox when textbox has more than one rows

Got rid of the duplicates, still some known bugs (the map clears when drawing something new, and cant delete drawings from the database for example)

GeoJSON data is now saved into one array. Also added min and max zoom, and removed zoom control from top left corner

Text box functionality, still not fully functional; Remove zoom control at top left corner; Add max and min zooms; Non-functional fix to dragging out of bounds
