- letters - if true, generated string may include alphabetic characters

-RandomSeed creates a random string based on a variety of options, using supplied source of randomness.
-If the parameters start and end are both 0, start and end are set to ' ' and 'z', the ASCII printable characters, will be used,
-unless letters and numbers are both false, in which case, start and end are set to 0 and math.MaxInt32, respectively.
-If chars is not nil, characters stored in chars that are between start and end are chosen.
-This method accepts a user-supplied *rand.Rand instance to use as a source of randomness. By seeding a single *rand.Rand instance
-with a fixed seed and using it for each call, the same random sequence of strings can be generated repeatedly and predictably.
