/**
 * Creates a new parse Parse.Query for the given Parse.Object subclass.
 *
 * <p>Parse.Query defines a query that is used to fetch Parse.Objects. The
 * most common use case is finding all objects that match a query through the
 * <code>find</code> method. for example, this sample code fetches all objects
 * of class <code>myclass</code>. it calls a different function depending on
 * whether the fetch succeeded or not.
 *
 * <pre>
 * var query = new Parse.Query(myclass);
 * query.find().then((results) => {
 *   // results is an array of parse.object.
 * }).catch((error) =>  {
 *  // error is an instance of parse.error.
 * });</pre></p>
 *
 * <p>a Parse.Query can also be used to retrieve a single object whose id is
 * known, through the get method. for example, this sample code fetches an
 * object of class <code>myclass</code> and id <code>myid</code>. it calls a
 * different function depending on whether the fetch succeeded or not.
 *
 * <pre>
 * var query = new Parse.Query(myclass);
 * query.get(myid).then((object) => {
 *     // object is an instance of parse.object.
 * }).catch((error) =>  {
 *  // error is an instance of parse.error.
 * });</pre></p>
 *
 * <p>a Parse.Query can also be used to count the number of objects that match
 * the query without retrieving all of those objects. for example, this
 * sample code counts the number of objects of the class <code>myclass</code>
 * <pre>
 * var query = new Parse.Query(myclass);
 * query.count().then((number) => {
 *     // there are number instances of myclass.
 * }).catch((error) => {
 *     // error is an instance of Parse.Error.
