Contract:

Quotes API:

1. loadQuotesList() - requests a list of quotes
2. loadQuote() - requests quote by id
3. createQuote() - quote creating

Unit:

Store middlewares:

1. Quote creation
   1. A quote should be created on server and be added to store by CREATED_SUCCESS
   2. When server responds error, action CREATED_FAIL should be created
2. Quote fetching
   1. Quote should be fetched from server and be added to store by FETCH_ONE_SUCCESS
   2. When server responds error, action FETCH_ONE_FAIL should be created
3. Quotes list fetching
   1. Quotes list should be fetched from server and be added to store by FETCH_ALL_SUCCESS
   2. When server responds error, action FETCH_ALL_FAIL should be created

Store reducers:

1. FETCH_ALL_SUCCESS must replace quotes list in store
2. CREATED_SUCCESS must append quote to the list in store
3. FETCH_ONE_SUCCESS must append quote to the list in store, if quote is not exist in list
4. FETCH_ONE_SUCCESS must do not append quote to the list in store, if quote is exist in list

Store selectors:

1. getQuotesList() - must return list of quotes
2. getQuoteIdMatch() - must return match of quoteId from location, if quoteId is exist
3. getQuoteIdMatch() - must return null, if quoteId is not exist
4. getQuoteIdByLocation() - must return quoteId from location, if quoteId is exist and valid
5. getQuoteIdByLocation() - must return null, if quoteId is not exist in location
6. getCurrentQuoteByLocation() - must return quote from store, if quote with id from location is exist
7. getCurrentQuoteByLocation() - must return null, if quoteId from location is not exist or invalid
8. getCurrentQuoteByLocation() - must return null, if quote with id from location is not exist
