/**
 * Class for generating SQL clauses that filter a primary query according to date.
 *
 * Is heavily inspired by the WP_Date_Query class in WordPress, with changes to make
 * it more flexible for custom tables and their columns.
 *
 * Date is a helper that allows primary query classes, such as WP_Query, to filter
 * their results by date columns, by generating `WHERE` subclauses to be attached to the
 * primary SQL query string.
 *
 * Attempting to filter by an invalid date value (eg month=13) will generate SQL that will
 * return no results. In these cases, a _doing_it_wrong() error notice is also thrown.
 * See Date::validate_date_values().
