isPrime() function/algo optimization: 
insted of taking all integers from 2 to K, take only odds
	since we know that the even prime is 2. This should in theory
	reduce the time to check primilaty to half.

improved interface 
- Accept key generation size. (not practical above 64-bit)
	- Decrypt from command args only for now
	- Catch Unicode Decode Error cuased by wong key or size.

Working interface. 
- Encrypt a signle word message. for now
    - Decrypt only with target private key
    - Runtime errors when using wrong key to decrypt or message too long.

Interfacing changes: 
- Split into methods.
    - Added a cli interface with commands 'gen <filename>' to generate keys
      and 'encrypt <message> <publicKey>' to encrypt a message
      to the passed key.
    - Read and save keys.
