Creates a hashtable, and inserts words into it.
The table is then printed before we free the memory allocated to it.
Note: The tablesize of the hashtable is determined by the first command line
argument if there is one, with a default table tablesize of 113.
The number of statistical snapshots to print is determined by the second
command line argument if there is one, with a default number of 10.
tablesize = the maximum number of positions in the hash table.
word = the string to be inserted into the hash table.
ht = the hash table using eith double hashing or linear probing.
snapshots = the number of statistical snapshots to be used.
@param argc the number of command-line arguments.
@param argv an array of strings containing the command-line arguments.
@return EXIT_SUCCESS if the program is successful.
