Exadel Smart Library (ESL) is the lightweight custom elements library that provide a set of super-flexible components

/**
 * CSS class manipulation utilities.
 *
 * Allows manipulating with CSS classes with the following set of sub-features:
 * - JQuery-like enumeration - you can pass multiple tokens separated by space
 * - safe checks - empty or falsy token sting will be ignored without throwing an error
 * - inversion syntax - tokens that start from '!' will be processed with inverted action
 * (e.g. addCls(el, '!class') - will remove 'class' from the element, while removeCls(el, '!class') adds 'class' to the element)
 * - class locks - you can manipulate with classes using `locker` option that takes into account the modification initiator.
 * That means the class added in 'locker' mode will not be removed until all initiators that requested add class have requested its removal.
