/**
 * Sort represents data sorting settings:
 *
 * - A config with a map of logical field => real fields along with their order. The config also contains default
 *   order for each logical field.
 * - Currently specified logical fields order such as field1 => asc, field2 => desc. Usually it is passed directly
 *   from end user.
 *
 * Logical fields are the ones user operates with. Real fields are the ones actually present in a data set.
 * Such a mapping helps when you need to sort by a single logical field that, in fact, consists of multiple fields
 * in underlying the data set. For example, we provide a user with a username which consists of first name and last name
 * fields in actual data set.
 *
 * Based on the settings, the class can produce a criteria to be applied to {@see SortableDataInterface}
 * when obtaining the data i.e. a list of real fields along with their order directions.
 *
 * There are two modes of forming a criteria available:
 *
 * - {@see Sort::only()} ignores user-specified order for logical fields that have no configuration.
 * - {@see Sort::any()} uses user-specified logical field name and order directly for fields that have no configuration.
 *
