Usage

    // CASE 1: Create random strings ( characters only ) of different lengths
    println("Random STRINGS - UPPER + lower case")
    println( "len 3 : " + string3()  )
    println( "len 6 : " + string6()  )
    println( "len n : " + stringN(9) )
    println()

    println("Random STRINGS - lower case only")
    println( "len 3 : " + stringN(3, allowUpper = false) )
    println( "len 6 : " + stringN(6, allowUpper = false) )
    println( "len n : " + stringN(9, allowUpper = false) )
    println()

    // CASE 2: Create Guid
    println("Random GUID")
    println( "dashes - yes : " + uuid() )
    println( "dashes - no  : " + uuid(includeDashes = false) )
    println( "casing - no  : " + uuid(includeDashes = false, upperCase = true) )
    println()

    // CASE 3: Create numbers of different lengths
    println("Random NUMBERS")
    println( "len 3 : " + digits3()  )
    println( "len 6 : " + digits6()  )
    println( "len n : " + digitsN(9) )
    println()

    // CASE 4: Create alpha-numeric strings ( chars + digits ) of different lengths
    println("Random ALPHA-NUMERIC")
    println( "len 3 : " + alpha3()  )
    println( "len 6 : " + alpha6()  )
    println( "len n : " + alphaN(9) )
    println()

    // CASE 5: Create alpha-numeric-symbol strings ( chars + digits + symbols ) of different lengths
    println("Random ALPHA-NUMERIC-SYMBOL")
    println( "len 3 : " + alphaSym3()  )
    println( "len 6 : " + alphaSym6()  )
    println( "len n : " + alphaSymN(9) )
