Constructor for FileRead.Here i check to see if a a .num file of the parsed file exists or not.If not...i then create it...print out
that this is the first time the program was run on this file and exit.A cookie is not actually printed out the first time jfortune will be
run on a given file
This is the method which reads in the no. in the .num of the input file and returns a random integer.The random int is chosen from between
0 and the number of cookies in the file.If the file contains null...i then scold the user saying that he/she was told that the file he/she
run jfortune on was not a fortune cookie file and that they should learn to interpret error messages and use google.
