Set the data format between front-backend and backend-training model.

We have the data format of the training data. Please @Dvangelion set the data format between the backend and training model.

[Dvangelion]

The model outputs the probability of user behaviours. i.e., {"adding to cart":0.5, "purchase":0.5}. I'll let you know after training is done.

Guys @baldandbrave @Dvangelion @Lyncis @smcheraghi , we need to specify the REST API queries that we could start preparing the frontend for the backend.

Example of queries that the front should send:

HTTP request	Action	Example
GET	Get all goods	http://backend.com/api/goods
GET	Get one good	http://backend.com/api/goods/1
POST	Create good	http://backend.com/api/goods
DELETE	Delete good	http://backend.com/api/goods/1
PUT	Update good	http://backend.com/api/goods/1

And example of data that will return for every query:
For example GET one good should return for front-end JSON like this:

{ 
"id": 1, 
"title" : 
"Santa pants", 
"cost": 99999, 
"recommendations" : [{
    "id": 2,
    "id": 3,
    "id": 4
    }]
}

After that I can create a fake json server that will send me the data like this and independently work on front-end
