/**
 * ESL Media Query
 * @implements EventTarget
 * Provides special media condition syntax - ESLMediaQuery
 * @author Alexey Stsefanovich (ala'n), Yuliya Adamskaya, Natallia Harshunova
 *
 * Utility to support extended MediaQuery features
 * Supports
 * - CSS MediaQuery matching check
 * - DPR display queries (`@x1|@x2|@x3`)
 * - Registered screen default sizes (breakpoints) shortcuts (`@[-|+](XS|SM|MD|LG|XL)`)
 * - Device and browser shortcuts (`@MOBILE|@DESKTOP|@IE`)
 * - Custom static shortcuts and custom query preprocessors
 * - `not` logic operation (can have multiple not operators before any term of the query)
 * - `or` or `,` logical operator (have a lowest priority)
 * - Query matching change listeners
 * - Implements {@link EventTarget}, compatible with {@link ESLEventListener}
 *
 * Building query process:
 *
 * [Building query logical tree] - [preprocess nodes queries] - [building native MediaQueryList nodes] - [query tree optimization]
