*) otp_enc_d: Performs the actual encoding. Runs in the background as a daemon. Listens on a particular port for the                       plaintext and the key. When a connection is made to otp_enc, it forks off a seperate process immediately so
              that it can handle concurrent connections. 
                  *) Syntax: otp_enc_d <listening_port> & 
              
*) otp_enc: Connects to otp_enc_d and asks it to perform a onetime pad style encryption as above. When it receives the 
              encrypted text, it outputs to stdout.
                  *) Syntax: otp_enc <plaintext_file_name> <key_file_name> <port> 
              
*) otp_dec_d: Performs exactly like otp_enc_d except that it decrpyts the ciphertext given to it.
                  *) Syntax: otp_dec_d <listening_port> & 

*) otp_dec: Performs excatly like otp_enc except that it asks otp_dec_d to decrypt ciphertext using a passed in ciphertet
              and key.
                  *) Syntax: otp_dec <plaintext_file_name> <key_file_name> <port>
                  
*) keygen: Generates a randomized key of specified length using the 26 capital letters and the space character.
                  *) Syntax: keygen <character_length>
