/**
 * Abstracts ad selection.
 *
 * The class allows to modify 'methods' (named callbacks) to provide ads
 * through `advanced-ads-ad-select-methods` filter.
 * This can be used to replace default methods, wrap them or add new ones.
 *
 * Further allows to provide ad selection attributes
 * through `advanced-ads-ad-select-args` filter to influence behaviour of the
 * selection method.
 * Default methods have a `override` attribute that allows to replace the
 * content. This may be used to defer or skip ad codes dynamically.
