# NTechLab homework for Python developer candidates

## Problem

> Напишите REST-сервис для поиска соседей. Основная функция - сервис должен
> позволить запросить K ближайших соседей пользователя N в радиусе M километров.
> Помимо этого сервис должен позволять выполнять простейшие CRUD-действия над
> пользователями - создавать пользователя с координатами (2D, на плоскости,
> сфере или геоиде - не суть), модифицировать информацию о нём (координаты,
> какое-нибудь описание, по желанию), удалять. У вас один миллион пользователей
> и один вечер.

## Installation

It's recommended that you use [conda](http://conda.pydata.org/miniconda.html)
to set up your Python environment.

``` bash
git clone https://github.com/balta2ar/ntechlab
cd ntechlab

conda create -n ntechlab python=3.5
conda install --file=requirements.txt
source activate ntechlab
```

## Running

``` bash
$ make unittest
python -m unittest test_model
