/**
 * This pipe should be used in pair with validateArrayElements function - it allows to distribute
 * errors for each position in array, from the object prepared by validateArrayElements.
 *
 * ```ts
 * errors = {
 *  "INNER_ARRAY_ERROR_minlength": {
 *    isArrayError: true,
 *    originalKey: "minlength",
 *    entries: [
 *      {
 *        index: 0,
 *        errorData: {
 *        requiredLength: 5,
 *        actualLength: 4
 *        }
 *      },
 *      {
 *        index: 2,
 *        errorData: {
 *          requiredLength: 5,
 *          actualLength: 3
 *        }
 *      },
 *    ]
 *  },
 *  "minlength": {
 *    requiredLength: 5,
 *    actualLength: 3
 *  }
 * }
 * ```
 *
 * ```html
 * <small *ngFor="let error of errors | extractArrayValidationErrors:index | keyvalue">
 *  {{ error.key | humanizeValidationMessage | translate: error.value }}
 * </small>
 * ```
 *
 * Above code renders only these error messages that are generated by Array entries.
