develop a Python class named OrderBook, that can model and store

an order book. note the following:

$$ OrderBook should be able to handle both the bid and ask sides.

$$ OrderBook should be able to handle both market and limit orders. A market order

should be matched immediately, while the limit order may or may not be filled fully.

A partially filled or totally unfilled order becomes part of the order book.

$$ Any any time, be able to output the best bid, best ask, bid$/$ask spread, and all market

depth.

$$ Any any price, ensure time priority of orders by matching orders that were placed first.
