Added all Sprint 2 resources.

Hey, so all resources should be functional. Sorry it took so long, but I had to rewrite quite a few stuff and quite a few stuff changed noticably from the beginning of previous sprint when I started implementing.

I have added coments to NetCdfManager to help me implement stitching of multiple files and all changes I made should be good for future implementation.

Curent urls are:
/feature/{{feature}}/area
/feature/depth - because vertical depth profile is a nonsense, so there will be only one type of requests
for future: /feature/{{feature}}/profile - or whatever will we call it will display vertical profile
