Description
randStr returns a randomly generated string using lowercase letters, and/or numbers and possible uppercase letters.
The length of the string can be set specifically or the function can choose a random length within a specified range. eg: "8,16" will generate a string 8 to 16 characters long: "5" would only generate strings with 5 characters.
The characters used are based on your own preference. You may build a 'charset' using any of the three words "alpha, numeric, and upper".
Alpha = a-z Upper = A-Z Numeric = 0-9
