Generates sets of numbers that can be used for the lottery, and more.
Version 2:
* Added error checking to the text fields, to prevent errors during processing of the random numbers.
* Made the list of generated numbers scrollable.
Note: There is a limitation on the output when lots of numbers are generated (e.g. 400 numbers, min 0, max 99, 10 numbers each will truncate in the output around 357).
Feel free to provide suggestions!
