      CustomError.call(this)      // adds CustomError functionality
      this.addCustomErrors({      // adds custom errors with addCustomErrors api
          smallBush: 'must have more then 10 branches'
      })
  
     if(this.branches < 3) throw this.CustomError('smallBush') // throw error with CustomError
