giver 2 strings : str1 and str2 , this method concatenates them by using the delimeter and restricting the size of the resulting string to maxlength . did not want to use namegenerator . _generate as that takes three inputs and if the third input is null it appends a random uuid - which we do not want in the users of this method .
