Write a program called randwords for the Unix command line that 

1) Reads in a list of words from a file.
   The format of this file is one word 
   per line.

2) Makes a fair random selection of n words from that
   list. This is sampling with replacement, a word
   may be chosen multiple times

3) Prints out the sample of words, one per line


Usage is

randwords wordlist n

where n is the number of words required and
wordlist is the wordlist.

This is easy to do with Python or Java but you
need a little shell script to meet the spec.

If the Python program is randwords.py, you
make a file called randwords that contains

python randwords.py $1 $2

and make it executable with 

chmod a+x randwords

Then you can just say (to the 
Unix shell)

randwords wordlist 12

and you should get 12 words chosen at
random from the wordlist.
