/**
 * Creates a query to retrieve a list of tasks.
 *
 * The `queryTasks()` function builds a query to retrieve a list of tasks and returns a `TasksQueryBuilder` object.
 *
 * The returned object contains the query definition which is typically used to run the query using the `find()` function. You can refine the query by chaining `TasksQueryBuilder` functions onto the query. `TasksQueryBuilder` functions enable you to sort, filter, and control the results that `queryTasks()` returns.
 *
 * `queryTasks()` runs with these `TasksQueryBuilder` defaults, which you can override:
 * - `limit(50)`
 * - `descending('_createdDate')`
 *
 * The functions that are chained to `queryTasks()` are applied in the order they are called. For example, if you apply `ascending('_createdDate')` and then `descending('_updatedDate')`, the results are sorted first by the created date and then, if there are multiple results with the same date, the items are sorted by the updated date.
 *
 * The following `TasksQueryBuilder` functions are supported for `queryTasks()`. For a full description of the `task` object, see the object returned for the `items` property in `TasksQueryResult`.
