/**
 * Base class.
 *
 * Fields are our core items and we'll use this class to sort them out a little.
 * Very useful, should be used to finish small tasks for field.
 *
 * Example:
 *
 * // Setup field
 * global $wpcf;
 * $my_field = new WPCF_Field();
 * $my_field->set($wpcf->post, wpcf_admin_fields_get_field('image'));
 *
 * // Use it
 * $my_field->save();
 *
 * // Generic instance can be found in global $wpcf.
 * global $wpcf;
 * $wpcf->field->set(...);
 *
 * !! BE CAREFUL !! not to disturb global instance if you suspect processing
 * current item is not finished. Core code sometimes use same instance over
 * few functions and places.
