Organize and simplify user interface
Organize and simplify user interface

The current user interface seems to place options in no particular order, which slows down the user's workflow. By providing some more organization, the learning curve will be easier for new users. In order to test the changes, I've entered each option and verified the appropriate output and action.

* Provide a hierarchy of verbs for the corresponding set of options.
* Alphabetize menu options for a second layer of organization.
* Simplify option statements and change the corresponding output in the appropriate places.
* Reorder mapping of number to function in the main while loop.
