Implement geo dataset caching and retrieval in C#

This project will build a new functionality to [url removed, login to view] backend.

First of all, please review our coding guidelines: [url removed, login to view]

Milestone 1. Implement CreateAndReloadDb method in PlacesLoader

Use the PostgreSQL connection string in the file

Method should be recreating city table (not recreating db)

Unit tests to verify that columns are created as expected

Milestone 2. Implement IPlacesServices on PlacesService. Method descriptions are in interface definition file. Then start using new service in [url removed, login to view]

Every method should be fully covered by unit tests

Places service should only go to DB the first time, after that it should cache cities in memory

FindPlacesByPartialMatch for 10 results should return the same list of cities as this call.

FindPlacesByPartialMatch should be using efficient data structure so that search is O(m+n) where m is number of letters in the searched substring and n is number of items to return

FindPlacesInArea should be using efficient data structure, so that we are partitioning cities efficiently and only look at required partitions around the center location

For more details please see[url removed, login to view]

Each milestone will only be accepted after pull request is reviewed and approved and all unit tests are written.

If interested, please send me a message with the following info:
