In assertive: Readable Check Functions to Ensure Code Integrity

Description

assertive contains lots of is_* functions to check the state of your variables, and assert_* functions to throw errors if they aren't in the right form.

Details

When the package loads, it creates a global option "assertive.severity" that determines what happens when an assert_* function's input fails the condition. By default, an error is thrown but it is possible to generate warnings or messages instead (see the examples).
