"""
A script to query the Amazon Web Services usage reports programmatically.

Ideally this wouldn't exist, and Amazon would provide an API we can use 
instead, but hey - that's life.

Basically takes your AWS account username and password, logs into the
website as you, and grabs the data out. Always gets the 'All Usage Types'

• Integers don't have a decimal place.
• Floats have a decimal place.
• Math mostly works the way it does on a calculator, and you can use parentheses to override the order of operations.
