/* I want to learn JavaScript, so I'm rebuilding my python SNAP MI calculator using JS
This calculates the total medical expense deduction for a SNAP household in Michigan 
using the following benefit rules: https://mdhhs-pres-prod.michigan.gov/olmweb/ex/BP/Public/BEM/554.pdf
If total medical expenses exceed $35/mo for senior or disabled households members,
the SNAP household can take a standard medical deduction of $165/mo. If their countable medical expenses exceed $200/mo, 
they can deduct the actual amount minus $35/mo */
