// | The 'NumberGenerator' class will generate large numbers by   |
// | concatenating strings of digits and saves them to their own  |
// | files.                                                       |
// |                                                              |
// | The 'GenerateNumber1' method generates the 1st number & saves|
// | it to the file called "number1.txt". It creates a new        |
// | Stopwatch instance to measure the time taken to generate the |
// | number and then prints the elapsed time.                     |
// |                                                              |
// | The 'GenerateNumber2' method does the exact same thing as    |
// | the 'GenerateNumber1 method, except creates a different file |
// | called "number2.txt".                                        |
// |                                                              |
// | The 'GenerateNumber' method generates a number and saves it  |
// | to a file with the given file name. It creates a new         |
// | StreamWriter instance to write to the file with the given    |
// | file name. The number is generated by concatenating strings  |
// | of digits using nested for loops. This method of creating a  |
// | number will make a number that's 3,220,383,898 bytes big.    |
