Create a function called howManyUntil(stopNum) where stopNum is an integer from 0 and 99

The function will randomly generate a number from 0 and 99 and keep generating random numbers until the number stopNum is generated. The function will return the number of random numbers that were generated in order to get the stopNum.

Example: If stopNum = 50 and the random numbers generated were 0, 4, 19, 50, then the function would return 4.
