/**
 * Stores all the state for an orderbook level, as described in <a href= "https://docs.coinapi.io/#order-book">https://docs.coinapi.io/#order-book</a>.
 * <p>
 * This class is multithread safe: it is <a href="http://www.ibm.com/developerworks/java/library/j-jtp02183.html">immutable</a>.
 * In particular, it is always <a href="http://www.ibm.com/developerworks/java/library/j-jtp0618.html">properly constructed</a>,
 * all of its fields are final,
 * and none of their state can be changed after construction.
 * See p. 53 of <a href="http://www.javaconcurrencyinpractice.com">Java Concurrency In Practice</a> for more discussion.
