Argument "type" validation

[crookse]

Summary

What:

Currently, the argument validation only checks to see that the arguments were specified:

• If an argument is missing, then an error shows up.
• If an extra argument was passed in, then an error shows up.

We should do argument validation on the "type" of the argument. For example, I want to make 10 test files using rhum like this:

rhum make 10

With the above command, Line should check that 10 is a number.

Why:

It would be nice to have built-in argument type validation.
