##To-Dos

• Tests! Write tests! How do I write tests?
• Figure out how to make this a proper package so that you can import scripts in the tests.py script without having to modify sys.path
• Figure out how to get this to work on someone else's computer without them having to add a symlink on their $PATH
• Standardize phone number entries
• Better use of argparse
• Allow search by partial name
• Allow -b phonebook to occur anywhere in command
• Case insensitive search
• Make names work without using quotes
• Add a config file where you can specify a default phone book to use. Add commands to edit this file without having to edit it manually
• Implement a http backend (phonebook lookup Tom -b 'http://mywebsite/phonebook' etc.)
• Add tab completion
